• For organisations that want to:

o standardise, streamline and automate

repeatable processes

o create embedded workflows

Enterprise

• Link Romax software to other CAE tools

o CAD interoperability and FE meshing

o Optimised multi-body dynamics and multi-physics

• The enablers for Enterprise, for

organisations that want to:

o enable easy collaboration

o increase productivity by linking multiple disciplines together

Slide 4CONFIDENTIAL

• Enables collaboration between CAD and Romax engineers

• Fast, error free data exchange (import and export

functionality)

• Allow faster model development times/more design

iterations

• Provides ideal mechanism for RxD engineers to

communicate issues/design recommendations

• Promotes the use of RxD earlier in the design process

• Allows easy auditing of designs

US OEM – Process for concept layouts

• Concept transmission development team wanted to streamline processes by:

o Speeding up modelling by using CAD FUSION to support the building of Romax models

o Using Dynamic FUSION to generate multibody models for use in driveline dynamic analysis and

plant models for driveline control development in GT-SUITE

o Using resulting transient dynamic loads to re-assess gear and bearing durability

• A joint project with Romax and Gamma Technologies is underway to assess the

methodology and test the new processes

o Phase 1 (completed): Romax and Gamma Technologies demonstrating the methodology on an

existing transmission design

o Phase 2 (in progress): Customer testing methodologies on a new design with support from

Romax and Gamma Technologies

Customised Reporting Recap

• Allows customers to design their own completely

customised RomaxDESIGNER reports in an easy

to use drag’n’drop environment

• Templates can include a variety of tables, images,

plots and comments

• Templates can be re-used and shared

• Huge time savings in data post processing

• Allows customers to standardise output from

RomaxDESIGNER

• Reduces errors

running

• Enables command line running of RxD

• Third party tools such as Excel or Isight can

be used to edit models and read results

• Can be used to allow running of 100s of

load cases

• Allows analysis automation

• Allows coupling to other analysis tools

• Will enable RomaxDESIGNER to be

embedded in automated processes

Comet Solutions

• Abstract Engineering Model - define a complete product system by

combining component and subsystem models at virtually any model

fidelity into a single parametric, multidisciplinary and multi-physics

model

• Reusable templates, capturing best practices

• Graphical – no scripting

• Achieved through custom objects – tags,

constructors, environment objects, etc.

Automation Example – Model

• Two-stage gearbox

• Target requirements: packaging,

mass, efficiency

• Variables: Lay shaft position, gear

macro geometry, housing geometry

• Other possible variables – shaft sizing,

bearing positions, etc.

Slide 14CONFIDENTIAL

Example Process

• Update CAD

• Mesh CAD as necessary

• Run RomaxDESIGNER with new configuration

– import FE, run analysis

• Report results

• Optimisation and appification possible

Conclusions

• Romax can offer comprehensive simulation technology and expertise enabling

collaboration and process improvement

• Process improvements can lead to significant benefits:

o Huge time savings

o Improved product quality

o Better utilisation of CAE tools already being used

• Through the use of 3rd party tools such as Comet and EASA:

o Specialist CAE tools can be made more widely accessible, breaking down expertise barriers,

removing bottle necks

o Complex automation opens new opportunities for innovation
