SIMULATION CAPABILITY

DATA GENERATED > Very High Volume!

WILLING TO SIMULATE (CAE like CAD 30 yeas ago)

LACK of METHODS to handle this avalanche of dataAnd even more important….

Simulation RESULTS HIGHLY DEPENDS ON SMART ANALYST

Considerations

PROCESS and METHODS variability

- Inconsistent use of methods and tools- Inability to share methods and process in “managed” way- Lack of audit trail for simulation

Simulation RESULTS > HIGHLY DEPENDS ON SMART ANALYST

Manually intense and ripetitive tasks- Load case and simulation setup- Post-processing and reporting

Considerations

WRONG TIME INVESTMENT

This situation has lead to….

Simulation is essentially used to VERIFY PROPERTYBut the its real potential can achieve:

?Really Necessary

Any system managing simulation information must show NOT only the final answer, but show the CONTEXT

that is used to get that answer.

Capturing the CONTEXT

Capturing the CONTEXT: METHODS

Capture the analyst/company BEST PRACTICE To achieve a certain output given a certain input given a certain CAE tool

Capturing the CONTEXT: PROCESS

STORE, DISTRIBUTE and MANAGE these “best practices”allow others designers, analysts, enterprise stakeholders toREUSE IT assuring the QUALITY OF RESULTS they deliver.

BEST PRACTICE IN CAE

Development of CAE-toolsFirst generation (1970-1995)

* Ascii command file based modeling* Vector graphics (Textronix terminals), later X11* No parametrisation

Second generation (1990-2005)* Interactive use and modeling* Parametric models inside application* Connection to generic graphic formats (e.g. IGES)* Programmability of command language* Inhouse libraries

Third generation (2005-)* Metamodeling software: SimXpert, CoMet, HyperWorks* Integration of several CAE-software and CADin in to

Multi View models* Support for CAE-prosesses and workflows* Support data management

• straw0001.avi•

Simulation tools• Native tools

– E.g. ADAMS, Abaqus, ANSYS, Nastran...– Work only in one domain of

CAD, FEM, MBS, CFD...– Native basic modeling– May contain own special models: e.g.

ADAMS/Hydraulics– Automation (programming on tool level)

• Metatools– E.g. SimXpert, Altair Hyperworks, CoMet– CAE-Application integration: Transformation of data

from one model to another CAD=>FEM => MBS– Interface to several native tools (CAD, FEM, MBS...)– Development of best integrated processes

• Process and data management– E.g. SimManager, Altair Data Manager, CoMet – Even some PDM-software may be applicable

Application integrationFor a human, managing engineering information, requires several viewpoints toreality. The views must show for each specialist their own view point to design object.

Build MULTIDOMAIN VIRTUAL PROTOTYPES with“HIGH” (Industrial value) FIDELITY:

1 single general multi domain environment does not exist (Modelica, Matlab vs despite of years of coding)!The actual approach is to connect different simulation environment (CAE SW) that deal with different aspect of the product (Transparent

Multi View Models)

APPLICATION INTEGRATION IS FUNDAMENTAL

CAD FEM

MBSCALC

Application integration: The commercial way

Direct convertersEasy to acquireCommercially available (if lucky)Direct to use

BUT!Dependent of BOTH applications => Application dependent(x 2)Version dependentAlmost never convert 100%Short and very unsure future support!
