At ANSYS Release 14.0, the license manager daemons (lmgrd and ansyslmd)have been upgraded to FLEXlm 11.9.1 (FLEXnet 11.9.1). We strongly recommend

that you upgrade to this version of the license manager, regardless of whether

you are upgrading to ANSYS Release 14.0.

You can now use the -setliclang option to change the language used byANSLIC_ADMIN and the ANSYS, Inc. Licensing Interconnect log file. This option

changes the language for all users running the ANSLIC_ADMIN utility (only the

server ANSLIC_ADMIN on Windows).

Release 14.0 - SAS IP, Inc. All rights reserved. - Contains proprietary and confidential information of ANSYS,Inc. and its subsidiaries and affiliates.2

Chapter 1: Global

To change the language setting locally for only the current session of the

ANSLIC_ADMIN utility, you can launch the utility using the -lang option.To always use this setting locally without having to set this command line

option each time, you can set an alias on UNIX/Linux or modify your Start

menu shortcut on Windows. Please refer to your operating system document-

ation for those instructions.

Chapter 2: Workbench

2.1. ANSYS Workbench 14.0

2.1.1. Design Point Enhancements

The following enhancements have been made to design point behavior:

Specify Design Point Update Order at the Project Level

You can now specify the order in which Design Points are updated at the project

level. When multiple Design Points share the same geometry or mesh, you can

improve the efficiency of the computations by specifying an update order in

which only those Design Points that change are updated. You can change the

sequence of updates manually, by a column sort, or by using the automatic op-

timization feature. For more information, see Design Point Update Order in the

Workbench User Guide.

The ability to change the order of Design Point updates is also available at the

DesignXplorer level. See Design Point Update Order in the DesignXplorer help

for more information.

Added Support for Simultaneous Update of Design Points via RSM

You can now use the Remote Solve Manager (RSM) to enable simultaneous exe-

cution of design points, allowing you to decrease the overall time required to

complete parametric what-if and design exploration studies. In the Parameter

Set Properties view, use the new Default Job Submission property to specify

how design points sent to Remote Solve Manager for update will be submitted.

For more information, see Updating Design Points via Remote Solve Manager

(RSM) in the Workbench Users Guide.



Submit Design Point Updates to RSM from DesignXplorer

You can now submit Design Point updates to RSM from DesignXplorer (DX). The

Pending state is also now supported for DX, which means if you submit a design

point update to RSM from DX, you can continue interacting with the project on

a limited basis and can view intermediate results of individual design point up-

dates via the Table of Design Points while the remote update is in progress.

Additionally, if you exit the project, when you reopen it the Resume button allows

you to resume the update.

For additional information, see Using Remote Solve Manager with DesignXplorer

in the DesignXplorer help.

2.1.2. Reporting

You can now write out a report of the current project in .html/.htm format. To

write a report, choose File> Export Report. The report will be written to the

user_files directory under the project directory by default. You can controlwhether the report opens by default using the Options>Project Reporting

settings.

The report contains basic project information, including a graphic of the systems

as shown in the project schematic, parameter and design point information, and

system and cell information. The specific information provided will vary depending

on the contents of the project. Additional information may be available from

the individual applications. Not all applications provide reporting information.

2.1.3. Workbench Options

Enhancements to Named Ranges Filtering Prefix for Microsoft

Excel Systems

For a project that includes a Microsoft Excel component, the Named Ranges

prefix can now be specified at the global level (via the ANSYS Workbench Options

dialog) as well as at the project level (via the Named Range Key property of the

Analysis component). Additionally, the Named Ranges filtering prefix now

conveniently defaults to blank or no filter.

For more information, see Microsoft Office Excel or Microsoft Office Excel Options

in the Workbench Users Guide.



2.1.4. Tighter Integration Between ANSYS Workbench and

EKM

The ANSYS Engineering Knowledge Manager (EKM) is a Simulation Process and

Data Management (SPDM) software system that allows you to store, share, report,

and operate on your simulation data in an accessible, web-based environment.

While EKM can operate as a stand-alone system, its integration with ANSYS

Workbench streamlines the process of storing, retrieving, and sharing your

Workbench projects within an EKM repository. Through the provided Repository

capabilities in the Workbench File menu, you have access to powerful SPDM

capabilities that allow you to:

archive completed projects or store works in progress to local or remote storage

share and collaborate on your projects

search projects based on names, dates, simulation type, or other criteria

retrieve your own projects or those shared by other users

ANSYS EKM provides access to a simulation data repository, which may exist

locally on your workstation (for individual repositories) or reside on a larger

dedicated server for enterprise-level data management.

2.1.5. Incompatibilities

There are no known incompatibilities to date in release 14.0.

2.2. DesignModeler Release Notes

The following general enhancements have been made in release 14.0:

Project Schematic Connections

You may now connect HFSS, Q3D, and Maxwell systems to downstream Geometry

cells via a provides-to connection in the project schematic.

Expanded Boolean Feature Capability

The Boolean feature now includes the ability to Imprint Faces from a list of target

and tool bodies. Either the target or tool bodies can be frozen.



DesignModeler Release Notes

Named Selection Feature Property Enhancement

An additional property named Export Selection is now available via the Named

Selection feature. Selection of the property via the Details View controls the

transfer of Named Selections to downstream applications such as ANSYS Mech-

anical. Note that the Named Selection option and the filter properties in the

Geometry cell of the Project Schematic are no longer available if the Geometry

cell specifies an ANSYS DesignModeler database.

GAMBIT Reader Upgrade

Beginning with the release 14 of ANSYS Workbench, GAMBIT real and non-real

(virtual, faceted, CAD) geometry may be processed. An option allows you to

choose whether to process both real and non-real data or just real only. Prior to

release 14, only GAMBIT real geometry (including hidden real geometry) would

be processed. By processing real and non-real geometry, the GAMBIT geometry

can be more accurately represented in ANSYS Workbench.

Transfer Enhancements

The transfer capabilities between ANSYS DesignModeler and ANSYS Mechanical

have been enhanced, most notably:

When transferring an ANSYS DesignModeler application to ANSYS Mechan-

ical for the first time, the order of bodies seen in ANSYS DesignModeler is

retained in ANSYS Mechanical.

Previously new bodies were created in ANSYS DesignModeler when

multibody parts, with shared topology created via the automatic method,

included overlapping surface bodies. Now the overlapping bodies are

transferred as separate bodies to ANSYS Mechanical instead of being asso-

ciated with one of the original bodies.

Vertex persistence in ANSYS Mechanical for concept parts transferred from

ANSYS DesignModeler has been improved although when refreshing older

databases in ANSYS Mechanical, vertex persistence might break the first

time. Once the vertex persistence is corrected the databases will persist for

further refresh operations.



Direct Entity Selection for Modeling Operations

Geometric entities such as faces, edges, vertices, or point feature points can now

be selected as input for the modeling operations. These operations include the

Extrude, Revolve, Sweep and Skin/Loft features.

Face Thickness Displayed by Color

Via the Graphics Options toolbar or the View menu, you can display face thickness

using colors. Each thickness is represented by a separate color.

Display Edge Direction

Via the Graphics Options toolbar or the View menu, you can display a models

edge directions. The direction arrow appears at the midpoint of the edge.

Automatic Promotion of Parameters

All parameters can now be automatically published to ANSYS Workbench when

geometry is imported or refreshed from the CAD source. The default for this

property is no, meaning all parameters are not published by default.

Display Vertices Option

Via the Graphics Options toolbar or the View menu, you can view all the vertices

in the model.

Toolbar Customization

Feature toolbars have been separated into smaller groups, making it easier to

access many features/tools directly from the toolbars.

Select Mode Functionality

Single Select and Box Select are now more quickly accessible by toggling the

right mouse button down, followed by the left mouse button down.

Hot Keys

New hot keys (short cut) are available for frequently repeated operations:




F3: Apply

F4: Cancel

F6: Toggle display (shaded+edges/shaded/wireframe)

F7: Zoom to Fit

Ctrl-A: Select All

Ctrl-P: Toggle Point selection filter

Ctrl-E: Toggle Edge selection filter

Ctrl-F: Toggle Face selection filter

Ctrl-B: Toggle Body selection filter

Ctrl-Z: Undo (sketching mode only)

Ctrl-Y: Redo (sketching mode only)

Ctrl-C: Copy (sketching mode only)

Ctrl-X: Cut (sketching mode only)

Ctrl-V: Paste (sketching mode only)

Electronics Tool Enhancements

The Electronics tool, available for preparing the model for thermal-flow analysis

using IcePak, is significantly enhanced with following improvements:

New ANSYS IcePak Object Types Three new IcePak object types are supported:

Axis Aligned Annular Cylinder: a cylindrical solid body with a concentric

cylindrical through-hole whose axis is aligned with one of the coordinate

planes.

Axis Aligned Conical Frustum: a solid conical frustum with the axis of the

conical surface aligned with one of the coordinate axis.

Axis Aligned Annular Conical Frustum: a solid conical frustum or cylinder

with a concentric cylindrical or conical through-hole whose axis is aligned

with one of the coordinate planes.

Enhanced Support for Polygonal Extrusion Level 2 geometry simplification

now supports polygonal extraction for parts with circular segments. Controls

available include:



Points on Arc: specifies the number of interior points that are placed at an

equal distance within the curved edges in the polygonal profile.

Length Threshold Percentage: specifies the threshold value to represent

the curved edges using interior points.

Enforce Axis: forces the DesignModeler application to look for polygon

profiles only in the normal plane of the selected axis.

Electronics Tool Usability Improvements

Part Structure Transfer to ANSYS IcePak: DesignModelers part-body

structure is retained during ANSYS DesignModeler to ANSYS IcePak model

transfer.

Rename Multiple Bodies in a Single Step: You can rename selected nodes

in the Tree Outline as a group. The single-step process is accessible via the

context menu.

Display of IcePak Icons for IcePak Bodies: DesignModeler now supports

IcePak icons in the tree outline for bodies converted into IcePak objects.

Shaft Feature

The Import Shaft Geometry feature has been introduced as part of ANSYS

DesignModeler. The feature uses a text file to generate a collection of line bodies

with circular or circular tube cross sections. You may specify the units of the data

in the text file and a base plane to orient the line bodies it creates.

Skin/Loft Property Enhancement

The Profile Selection method property in the Skin/Loft feature includes two new

options to select either all or individual profiles.

Automatic Freeze during Slicing

Active bodies are now frozen automatically during use of the Slice feature, Slice

Targets property, and the Slice Material operation. In addition, ANSYS Design-

Modeler no longer requires that a model be completely frozen before allowing

slice operations.




AutoCAD Support

ANSYS DesignModeler now supports the AutoCAD file format in both plug-in

(requires CAD system to be running) and pseudo-reader (does not require CAD

system to be running) modes.

Error Messages

Error reporting has been improved for the Share Topology feature and Import/At-

tach features to give more detailed error information.

BladeEditor (p. 14)

Vista CCD (p. 15)

Note

After reviewing these release notes, you are encouraged to see Usage

Notes, which describes some known TurboSystem-related workflow

issues and recommended practices for overcoming these issues.

2.3.1. ANSYS BladeModeler

2.3.1.1. BladeGen

BladeGen is a geometry-creation tool for turbomachinery blade rows.



TurboSystem Release Notes

2.3.1.1.1. BladeGen New Features and Enhancements

Vista AFD is no longer available from BladeGen, after having moved to Workbench.

For details, see "Vista AFD".

2.3.1.1.2. BladeGen Limitations

For the Quasi-Orthogonal Area Graph, in some special cases involving sharp

bends in the hub or shroud, the Quasi-Orthogonal Area with the blades can give

incorrect results. This is the case regardless of the flow angle correction. The area

curves without the blades are not affected by this defect.

2.3.1.2. BladeEditor

ANSYS BladeEditor is a plugin for ANSYS DesignModeler for creating, importing,

and editing blade geometry.

2.3.1.2.1. BladeEditor New Features and Enhancements

Camberline Thickness Mode

The workflow has been changed so that camberline/thickness definitions

now appear exclusively as sub-features of the Blade/Splitter feature. For

details, see Blades made using Camberline/Thickness sub-features in the

TurboSystem User Guide. The splitter camberlines can now reference data

from the main blade. For details, see Camberline/Thickness Definition Sub-

features of Independent Splitters in the TurboSystem User Guide.

Auxiliary view

This view now shows meridional curvature for the hub and shroud. For de-

tails, see Meridional Curvature View in the TurboSystem User Guide.

Added Blade Clearance properties to the Blade feature. For details, see Blade

Feature in the TurboSystem User Guide.

User-defined layers

You can create layers based on sketch curves. For details, see FlowPath

Feature in the TurboSystem User Guide. Data layers in BladeGen models are

converted to user-defined layers when loaded into BladeEditor.

BladeEditor has been made consistent with BladeGen in that, by default, both

now read and write files that express angles in radians instead of degrees.



2.3.2. Vista CCD

Vista CCD is a program for the preliminary design of centrifugal compressors.

See "TurboSystem: Vista CCD" for details on using this new version of Vista CCD.

Vista CCD was developed by PCA Engineers Limited, Lincoln, England.

2.3.2.1. Vista CCD New Features and Enhancements

Vista CCD has been improved to work for a wider range of operating conditions.

Enhancements to Vista CCD:

Real gas capability was enhanced for "highly imperfect" gases.

2.3.2.2. Vista CCD Incompatibilities

The new version of Vista CCD is not backwards-compatible with versions earlier

than Release 13.0. You must use the earlier versions if you want to view the Vista

data for previous BladeGen models.

2.4. Meshing Application Release Notes

This release of the Meshing application contains many new features and enhance-

ments. Areas where you will find changes and new capabilities include the fol-

lowing:

Resuming Databases from Previous Releases

Note the following when resuming databases from previous releases:

Upon import of a legacy model into release 14.0, suppressed virtual topology

entities will be deleted. This includes any virtual topology entities that were

suppressed manually (for example, by right-clicking on the virtual topology entity

in the Tree Outline and selecting Suppress from the context menu), but it does

not include virtual topology entities that are suppressed because the body con-

taining them is suppressed. If entities are deleted, a warning message will be is-

sued advising you to import the model into an earlier release, unsuppress the

affected entities, and save the model for use in release 14.0. Also see the Virtual

Topology section below.



Meshing Application Release Notes

At release 13.0, all mesh connections were pre, but at release 14.0, all mesh

connections are post. Upon import of a release 13.0 database into release 14.0,

all mesh connections are updated accordingly.

When assembly meshing algorithms are used in release 14.0, Program Controlled

inflation is not supported on solid bodies. The solid bodies will not be inflated.

If you import a release 13.0 database that specifies the CutCell meshing algorithm

and Program Controlled inflation is defined on a solid body, you must either

change the Fluid/Solid designation of the solid body to Fluid or set Use Auto-

matic Inflation to None and define local inflation controls to obtain the release

13.0 behavior. Also see the Assembly Meshing section below.

Contact regions are now resolved automatically as interfaces for use in ANSYS

FLUENT. In support of this change, if you import a legacy model with all of the

following characteristics into release 14.0, a message will be issued to advise you

that if you do not want the contact regions to be resolved, you should delete

them:

Physics Preference is set to CFD.

Solver Preference is set to Fluent.

Contact regions are defined.

However, if you do want the legacy contact regions to be resolved, you must

clear and regenerate the mesh in the release 14.0 Meshing application prior

to exporting/opening the mesh in ANSYS FLUENT.

Also see the Miscellaneous Changes and Behaviors section below for re-

lated information.

The logic for translating material properties of bodies/parts to continuum zone

types when a mesh is exported to ANSYS FLUENT format has changed in release

14.0. Body/part names and Named Selection names are no longer considered.

However, upon import of a legacy model into release 14.0, the Fluid/Solid ma-

terial property for each body will be set based on pre-14.0 rules.

Special handling of sheet bodies occurs during migration based on whether

the model is 3D (not planar in the XYZ plane) or 2D (planar in the XYZ plane):

If 3D or in cases in which only surface mesh is being exported, migration of

sheet bodies is skipped. The pre-14.0 rules are not used to interpret the

naming of the sheet bodies, and no material properties are assigned to them.

If 2D, pre-14.0 rules are applied to the sheet bodies as follows:



If Named Selections, part names, and/or body names are defined, they

are applied according to the following priority:

Named Selections defined for the underlying faces in a sheet body.

In such cases, a message will be issued indicating the Named Selection

definition for the faces will override the Fluid/Solid material property

for the sheet body.

Named Selections defined for sheet bodies

Part names

Body names

This means that when defined, Named Selections for underlying faces

take highest priority, then Named Selections for sheet bodies, then

part names, then body names. An exception occurs if a part name

would result in a material property of Solid but a body name would

result in a material property of Fluid. In such cases, the sheet body

is transferred as a Fluid.

If no Named Selections, part names, or body names are defined, the sheet

bodies are transferred as continuum zones and the same rules as in the

3D case are applied.

A message will be issued if the migration results in a change to the material

properties of any body, in which case you can perform a right mouse button

click and select Go To Object from the context menu to select the object

in the Tree Outline that is responsible for the message. Also see the FLUENT

Export section below.

Assembly Meshing

Assembly meshing refers to meshing an entire model as a single mesh process,

as compared to part- or body-based meshing, in which meshing occurs at the

part or body level respectively. If the assembly meshing Method control (de-

scribed below) is set to None, ANSYS Workbench meshing operates at the part

level, but if it is set to CutCell or Tetrahedrons, the entire assembly will be

meshed at one time using the selected assembly meshing algorithm.

Assembly meshing should be able to produce conformal mesh between parts if

their faces are overlapping.




Assemblies can also be meshed using part-based meshing methods, but in such

cases the mesher operates one part at a time, and therefore cannot mesh virtual

bodies or evaluate parts that occupy the same space.

The following enhancements have been made in support of assembly meshing

at release 14.0:

Assembly MeshingOverview

The Assembly Meshing group of global mesh controls is now available. You can

use one of the controls, called Method, to choose either CutCell or Tetrahedrons

as your strategy for assembly meshing. CutCell is available only in the Meshing

application, and only when Physics Preference is set to CFD and Solver Prefer-

ence is set to Fluent. Tetrahedrons is available in both the Meshing application

and the Mechanical application, regardless of Physics Preference and Solver

Preference settings.

The Tetrahedrons assembly meshing algorithm is a derivative of the CutCell

algorithm, with strengths and weaknesses similar to those of CutCell. The

Tetrahedrons method starts from the CutCell mesh and through various

mesh manipulations creates a high quality unstructured tet mesh.

Named Selections are supported for assembly meshing. However, the

mesher will not fail if a Named Selection is not protected; it will issue a

warning.

Assembly MeshingGlobal Improvements

A Fluid/Solid material property setting is now available in the Meshing applica-

tion. This property, which appears in the Details view if you select a prototype

(i.e., Body object) in the Tree Outline, allows you to control the physics that occur

on a model. It affects how material properties are translated when you export a

mesh for use in ANSYS FLUENT. Valid options are Fluid, Solid, and Defined By

Geometry. When set to Defined By Geometry, the value is based on the Flu-

id/Solid material property that was assigned to the body in the DesignModeler

application. The Fluid/Solid property also appears in the Details view if you select

a Virtual Body object in the Tree Outline, but in such cases it is always set to

Fluid (read-only). This property is not available if you are using the meshing

capabilities from within the Mechanical application.

When setting local (scoped) sizing controls, the Body of Influence option for

Type is supported. The body of influence cannot be scoped to a line body.



The default for Proximity Size Function Sources has been changed to Edges.

This setting is sufficient for most models.

Assembly MeshingVirtual Bodies

In principal, there are two approaches for extracting fluid domains from CAD:

1. For internal flow, cap the inlets, outlets, and any other leakage of the solid do-

main and perform a Boolean subtraction operation inside the CAD system to

extract the flow volume.

2. For external flow, create a large external domain outside of the solid object,

perform a Boolean subtraction operation inside the CAD system, and delete

any remaining interior voids inside the solid.

However, depending on the number of solids and the quality (or cleanliness)

of the original CAD, these Boolean operations may fail.

Assembly meshing provides the means of extracting and meshing the flow

volume within both these scenarios in one operation, and hence eliminates the

need for the Boolean operations. To use these approaches, capping faces or

large external domains need to be created in the CAD system. These fluid domains

are represented by virtual bodies in the Meshing application. You also need to

define a coordinate system at any location inside the extracted fluid domain.

When you insert a virtual body into the Tree Outline, a Virtual Body Group,

representing the fluid type, is created with a Virtual Body as a child object. In

the Details view settings for the Virtual Body, you associate the material point

with the coordinate system.

Often, you are interested only in the fluid flow and hence the solid mesh is not

needed. The Keep Solid Mesh control determines whether the mesh for any

body marked as a solid is discarded or kept.

Since meshing all of the solids and then discarding the solid mesh would not

be efficient, you can provide the Fluid Surface in addition to the material point

inside the Virtual Body definition, thereby eliminating the need to mesh the

solid and leading to improved meshing performance by a factor of two or more.

To aid in finding all the faces that are needed to create a Fluid Surface object,

a new Extend to Connection option has been added to the Extend Selection

drop-down menu. Before you use this tool, make sure that the global size function

option Min Size/Proximity Min Size is set appropriately and that the Find

Contacts tool has been executed.




Due to missing rubber seals, bolt threading, or other simplifications, the solid

CAD may not be watertight. In these situations, the assembly meshing al-

gorithms can trace the leaks and display their leak paths graphically to help you

with troubleshooting.

Leakage usually occurs if any contact is larger than 1/10 of the local minimum

size. If a leak is up to 1/3 of the local minimum size, you can use contact sizing

to close the gap.

Assembly MeshingDiagnostics Tools

For performing diagnostics for assembly meshing problems, the Find Thin Sec-

tions and Find Contacts tools are available. These tools return lists of contact

regions based on the global size function option Min Size/Proximity Min Size,

which should be set appropriately before you invoke them. When Find Thin

Sections is executed (using RMB), each of the contact regions it returns contains

faces on the same body that will not be resolved properly based on the current

global minimum size. When Find Contacts is executed (using RMB), the tool re-

turns a list of contacts, which is used to pass feature information down to the

meshing algorithm. The Find Contacts tool is particularly useful for assemblies

in which fillets of bodies are adjacent to other bodies, forming a sharp angle.

Find Contacts will preserve the edges of these fillets independent of the feature

angle settings.

Related to these tools, the Use Range option has been added as a global

connection setting so that searches can operate on a range of values.

Assembly MeshingInflation

For the CutCell algorithm, inflation is neither Pre nor Post. Rather, it may be

considered a hybrid of the two, in that the technology used is like that of the

Pre algorithm, but inflation occurs Post mesh generation. For the Tetrahedrons

algorithm, Pre inflation is used, with inflation behaviors and limitations very

similar to those of the Patch Conforming Tetrahedron mesh method.

When an assembly meshing algorithm is being used, a mixture of global (auto-

matic Program Controlled) and local (scoped) inflation is not supported; you

must choose between the two approaches:

For inflation on virtual bodies, you must use automatic Program Controlled

inflation; you cannot use local controls to inflate virtual bodies. Thus in gen-

eral, if you are using virtual bodies to represent flow volumes in your model,

plan to use automatic inflation. Automatic inflation is specified globally by

setting Use Automatic Inflation to Program Controlled. With Program



Controlled inflation, faces on real solid bodies will inflate into the virtual

bodies. The Fluid/Solid designation on real bodies will be respected (that is,

faces on real fluid bodies will inflate into the fluid region, but the solid region

will not be inflated).

Alternatively, you can set Use Automatic Inflation to None and define local

inflation controls. This approach is appropriate if your model contains real

bodies that represent the fluid regions.

If any global or local inflation settings are modified and you re-mesh, only

the inflation layers are regenerated. This is true for both approaches, regard-

less of which assembly meshing algorithm is selected.

Assembly meshing algorithms support 3D inflation only. Unlike 3D inflation for

part/body level meshing, for assembly level meshing the scoped body and the

face that you select to be the inflation boundary do not have to be on the same

part.

By default, Gap Factor is set to 1.5 for the CutCell algorithm. For the Tetrahed-

rons algorithm, Gap Factor is set equal to the value that is specified for non-

assembly mesh methods (0.5 by default) and is updated accordingly if that value

is changed.

Assembly MeshingAdditional Tools

The new Sharp Angle Tool lets you control the capture of features with sharp

angles, such as the edge of a knife or the region where a tire meets the road. It

can also be used for improved feature capturing in general, even if the faces

that you pick to define a control do not form a sharp angle. The Sharp Angle

Tool is available only when assembly meshing algorithms are being used and

ensures that the desired features are captured in the assembly mesh.

Mesh groups are used to merge adjacent bodies into one body. The grouping

tells the mesher to treat certain solid parts as one part and ensures that the mesh

generated on the combined parts is associated with the mesh of the selected

master body. Mesh grouping is available only when assembly meshing algorithms

are being used. Mesh Group objects appear in the Tree Outline under the Mesh

object.

Also see the Miscellaneous Changes and Behaviors section below.

Post Pinch Controls and Mesh Connections

At release 14.0, either the pinch control feature or the mesh connection feature

can be used to join shell meshed parts after meshing.




In support of this functionality, a new option for specifying PinchBehavior is

available for local pinch controls. Edge-to-edge pinch controls can be pre or

post, but edge-to-face pinch controls are always post. When set to Pre, pinches

are processed before face meshing, and when set to Post, pinches are processed

in a separate step after all meshing is complete.

At release 13.0, all mesh connections were pre, but at release 14.0, all mesh

connections are post. The mesh connection feature leverages the Post pinch

technology to automatically generate Post pinch controls internally at meshing

time. This technology allows mesh connections to work across parts so that a

multibody part is no longer required.

The Snap to Boundary option, which was already available for edge-to-face

pinch controls, is now supported for edge-to-face mesh connections as well.

When Snap to Boundary is set to Yes (the default) and the distance from a

slave edge to the closest mesh boundary of the master face is within the specified

snap to boundary tolerance, nodes from the slave edge are projected onto the

boundary of the master face. In addition, you have more control over the snap

type and snap tolerance. By default the snap tolerance is set equal to pinch tol-

erance, but setting the Snap Type option to Manual Tolerance lets you override

it. Alternatively, you can set Snap Type to Element Size Factor to enter a factor

of the local element size of the master topology. For edge-to-edge pinch controls

or edge-to-edge mesh connections, the snap tolerance is set equal to the pinch

tolerance internally and cannot be modified.

When used on parts and bodies that have been joined by mesh connections or

post pinch controls, the Clear Generated Data option now works as follows,

where the "base" mesh, which is stored in a temporary file, is the mesh in its

unsewn (pre-joined) state:

If a base mesh is available, the mesh is reverted to the base mesh and the reques-

ted parts/bodies are cleared.

If no base mesh is available, the entire mesh is cleared and a warning message

is issued. Reasons the base mesh may not be available include situations in which

you have deleted your temporary files, exported a .mechdat file for someone

else to use, or moved your project database to a different computer.

Selective Meshing (formerly Direct Meshing)

The selective meshing process (formerly known as direct meshing) has been

improved at release 14.0. You can use the Mesh worksheet to create a selective

meshing history, so that your meshing steps can be repeated in the desired se-



quence for any geometry update or re-mesh operation. You can populate the

worksheet either by recording meshing steps as you perform them or by adding

meshing steps to the worksheet manually. In each meshing step, the bodies as-

sociated with a given Named Selection are meshed. For greater flexibility, you

can activate and deactivate steps in the worksheet to control whether they are

processed or skipped during mesh generation and other worksheet operations.

The worksheet is dockable. Once you toggle it on, you can move it to the desired

location which will persist whenever the Mesh object or one of its child objects

is highlighted in the Tree Outline. For example, you may want to dock the

worksheet alongside the Geometry window, allowing you to view both at once.

Also see the Miscellaneous Changes and Behaviors section below.

Patch Conforming Meshing

A new global group of meshing controls, called Patch Conforming Options,

has been added at release 14.0. The first of these new options is Triangle Surface

Mesher, which determines which triangle surface meshing strategy will be used

by patch conforming mesherseither Program Controlled or Advancing Front.

When set to Program Controlled, the mesher determines whether to use the

Delaunay or advancing front algorithm based on a variety of factors such as

surface type, face topology, and defeatured boundaries. When set to Advancing

Front, the mesher uses advancing front as its primary algorithm, but falls back

to Delaunay if problems occur.

The Triangle Surface Mesher control has no effect on parts or bodies being

meshed with the Patch Independent Tetra mesh method. The Patch Conform-

ing Options group of controls is inaccessible when an assembly meshing al-

gorithm is selected.

MultiZone Mesh Method

The following enhancements related to the MultiZone mesh method have been

made at release 14.0:

Improved handling of imprints. This includes imprinting through multiple bodies,

through multiple levels in the same body, and through long stretches of side

faces. Improvements have been made to submapping of cylindrical faces with

side cutouts, especially those used as side faces along the sweep path.

Support for match controls on faces has been added, with certain limitations.




A new Prism option is available for Mapped Mesh Type. The Prism option

generates a mesh of all prism elements for the part the method is scoped to.

This option is sometimes useful if the source face mesh is being shared with a

tet mesh, as pyramids are not required to transition to the tet mesh.

Improved handling of edge splits.

Uniform Quad/Tri and Uniform Quad Mesh Methods

The following enhancements related to the Uniform Quad/Tri and Uniform Quad

mesh methods have been made at release 14.0:

Edge, face, and body sizing are supported. When using edge sizing, you can

specify a Type of either Element Size or Number of Divisions. For face and

body sizing, Type is always Element Size. The Sphere of Influence and Body

of Influence options are not supported for Uniform Quad/Tri and Uniform Quad.

The Uniform Quad/Tri and Uniform Quad mesh methods support mesh connec-

tions and pinch controls (post pinch only).

Size Function Handling

The following enhancements and guidelines relate to size function handling at

release 14.0:

When Use Advanced Size Function is set to On: Proximity and Curvature, you

now have the option to specify a global Proximity Min Size to be used in

proximity size function calculations, in addition to specifying a global Min Size.

By default, Proximity Min Size is set equal to the default of Min Size. Any feature

that operates based on minimum element size (for example, Defeaturing Toler-

ance, Pinch Tolerance, and Find Thin Sections), will now be based on the smaller

of the two minimum size values.

When Use Advanced Size Function is set to On: Proximity, only Proximity

Min Size is available.

In cases where you applied a hard size that is smaller than the minimum size,

there may be a poor size transition in proximity to the entity with the hard size.
