• Place lumped mass at CG

• Option to combine bodies into 1 lumped mass

• Option to offset location and add additional mass

• Option to overwrite mass calculation with a user defined mass



Mesh Primitives

Objective: Create meshes based upon analytical shapes

Implementation: Mesh Primitives commands

• 0D, 1D, 2D, and 3D meshes

• Creates nodes and elements in the absence of geometry

• Primitive geometry: points, lines, circles, Cartesian planes,

Cartesian boxes, and spheres

Recipe support for all types so editing is available after creation



Fill Holes in a Mesh

Objective: Fill holes in a mesh as needed for solid or shell analyses

Implementation: Introduce a new command and new selection

methods

• Mesh from Boundary

Remove Ribs

Objective: Identify and remove elements that

define a rib feature in the FEM

Implementation:

Remove Ribs command that detects

rib elements based upon

• Detection parameters

• Maximum elements in rib

• Maximum rib area

• Thin rib as a minimum % of nodes on

rib edge

Option to retain elements identified as a

rib by removing ribs from the list

Option to create groups from the ribs



2D Mesh Multi-Block Decomposition

Objective: Produce more structured 2D meshes

Implementation:

Extend multi-block decomposition in 11 compared to 10

• Decomposes faces into more rectangular regions

• REQUIRES use of Free Mapped Meshing option to produce

structured meshes; subdivision/paver also influence result

Without multi-block, with subdivision With multi-block, free mapped, and paver



Improved Feature Capture in 2D Meshes

Objective: Produce a mesh that better represents the CAD feature

Implementation:

Smarter geometry abstraction with CAD curvature abstraction

• When abstracting blends, consider abstracting to the blend crest

if blend is larger than Minimum Element Length, but smaller than

2X MEL

• Avoids turning a blend into a chamfer and an overly stiff

representation



Adaptive Meshing Updates

Zones

• Suppression, refinement, singularity

Singularity detection

• Implement special refinement method around singular regions

Bounding volumes

• Analytical volumes used to define suppression and refinement zones

Refine mesh from an element size (length) spatial field

Cutoff stress (minimum stress norm) for absolute steady stress convergence

LOG file

Keep solver files for all iterations

Adaptive analysis of normal modes solutions

Adaptive analysis in the context of AFEM



Refinement Zone – Conditionally Converged Solution

Define a refinement zone around the blend notch

• Cylinder

Refine in the zone, but nowhere else

Error after 5 iterations in the zone: 4.5 MPa (Target: 5.0 MPa)

Max error in the model: 12.4 MPa

Model converged because error outside the refinement zone is

ignored



0D Mesh Geometry Weighted Distribution of Mass

Objective: Apply additional mass to a model to represent a coating

on geometry

Implementation:

• Update the 0D Mesh command to support geometry weighted

average distribution of a total mass

• NX 10 methods (Distribute Mass, Yes/No) still supported

• Applicable to NX Nastran and Simcenter Multiphysics CONM2

• User specifies total mass for a mesh and selects geometry

• Simcenter creates a lumped mass at each node on the geometry

and bases the mass values on average length/area/volume at

each node



Tensor Based Loads: Initial Stress/Strain

Objective: Create a load based upon tensor data such as initial

stress or strain

Implementation:

New load type specific to initial stress/strain

• Requires a spatial field

format and contents.

• The Conflict

• Automating the complete Report creation will deliver the Standardization

requirement. But each automation becomes a unique and not a

Generalization solution.

Report Writer delivers the process (framework) and the granular automation

to achieve Standardization, and the flexibility to define company or user

defined layout, format and contents to provide Generalization.

Example Report format.



Microsoft Office – Standard Tools to Create Reports

of this powerful tool by writing the Simcenter data directly into the .docx file using Word’s

OpenXML file format.

• Word has all the required word processing functionality including styles, formats, headers, footers,

tables, geometry for boxes, images etc for defining a Report template.

• Simcenter will directly write the text, table and image data into the Word file at specified locations

(keywords) and inherit the format/style of that keyword (ie bold & italic).

• From Word, other file formats can be created (eg pdf, html, etc).
