Introduction

3 CAE today is used increasingly for initial design,

simulation, verification, certification, etc.

3 across industries like auto, aero, space, shipbuilding, plant

engineering

3 for various disciplines including static, (fatigue) strength, and

vibration analysis, CFD, dynamic systems, plastic deformations

(crash), ...

3 However ...

3 there is no common database that integrates the various digital

simulation tools

3 simply using PDM for CAE can’t satisfy simulation specific

requirements

Top Issues in the CAD/CAE Integration

Domain

(as identified by FENet)

3 Missing Integration of tools for structural analysis and life

cycle analysis

3 geometry, loads, material property databases, …

3 Lack of integration of engineering analysis into design and

development processes

3 Use of incompatible legacy models and data

3 Need for improved data consistency

3 Missing use of standards like OMG PLM Services

3 Insufficient CAE-to-CAD modification feedback

(7)

Keep inter-relations of CAE information

with other domains

3 Close interrelation exists naturally between information in product

design and simulation

3 CAE activities verify function or behavior of the product design

3 CAE often provides the "intial value" for design in developing (global) boundary

conditions etc.

3 Changes in one domain cause related activities in others

3 typically iterative processes, often with feedback loops

3 These logical interrelations can’t easily be made persistent today

3 Because of insufficient possibilities to trace dependencies:

3 Who is affected by this change?

3 What are the implications of this change?

3 Different granularity of CAD and CAE data

3 analysis relevant aspects often not visible at the part level

3 relationships between CAD and CAE need to cross levels of granularity

3 today there is no solution to represent the creation processes of CAE information

CAD - CAE Integration Use Cases

3 Browsing PDM system(s) and export of metadata, structure and

geometry, already considering version information, last_modified,

configuration and effectivities

3 Structural data filtering for CAE relevance

3 Import of structure/metadata and CAD models into the Simulation Data

Management (SDM) system

3 Export of analysis results from SDM and import into the PDM system

3 Identify delta and update SDM system with changes on CAD side

Summary

3 CAE is increasingly used in the product development process, therefore data

management and integration becomes more and more significant

3 The integration of CAD and CAE leads to a new and often underestimated level

of complexity

3 Heterogeneous environments – as the CAE world clearly is - demand

vendor-independent, standard based approaches

3 OMG PLM Services is an ready to use industry standard for integration topics

on masterdata, product structure and configuration level

3 Products like PROSTEP’s OpenPDM

®

_{are available and already established in}

CAD/PDM integration, synchronization and collaboration scenarios
