Introduction

� CAE today is used increasingly for initial design, simulation, verification, certification, etc.� across industries like auto, aero, space, shipbuilding, plant

engineering� for various disciplines including static, (fatigue) strength, and

vibration analysis, CFD, dynamic systems, plastic deformations (crash), ...

� However ...� there is no common database that integrates the various digital

simulation tools� simply using PDM for CAE can’t satisfy simulation specific

requirements


Enterprise Application Integrationfor Technical Product Data – Current Situation

� Methods to manage CAD data and processes (PDM) are wellestablished in today's industries

Meta information exchanged between PDM systems, but always remains within the design domain– scope stays

unchanged

One major type of design tool: the “CAD system” –high information content overlap


Enterprise Application Integrationfor Technical Product Data – A new Situation

� The use of different data management tools across domains creates challenges regarding (e.g. data ownership, dependency, traceability)

Top Issues in the CAD/CAE Integration Domain (as identified by FENet)

� Missing Integration of tools for structural analysis and life cycle analysis� geometry, loads, material property databases, …

� Lack of integration of engineering analysis into design and development processes

� Use of incompatible legacy models and data� Need for improved data consistency� Missing use of standards like OMG PLM Services

� Insufficient CAE-to-CAD modification feedback

• Manage CAE information during the product lifecycle

• Keep inter-relations of CAE information with other domains


Keep inter-relations of CAE informationwith other domains

� Close interrelation exists naturally between information in product design and simulation� CAE activities verify function or behavior of the product design� CAE often provides the "intial value" for design in developing (global) boundary

conditions etc.

� Changes in one domain cause related activities in others� typically iterative processes, often with feedback loops

� These logical interrelations can’t easily be made persistent today� Because of insufficient possibilities to trace dependencies:

� Who is affected by this change?� What are the implications of this change?

� Different granularity of CAD and CAE data� analysis relevant aspects often not visible at the part level� relationships between CAD and CAE need to cross levels of granularity� today there is no solution to represent the creation processes of CAE information

CAD - CAE Integration Use Cases

� Browsing PDM system(s) and export of metadata, structure and geometry, already considering version information, last_modified, configuration and effectivities

� Structural data filtering for CAE relevance

� Import of structure/metadata and CAD models into the Simulation Data Management (SDM) system

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

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

� Result: Linked CAD and CAE Processes

Summary

� CAE is increasingly used in the product development process, therefore data management and integration becomes more and more significant

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

� Heterogeneous environments – as the CAE world clearly is - demand vendor-independent, standard based approaches

� OMG PLM Services is an ready to use industry standard for integration topics on masterdata, product structure and configuration level

� Products like PROSTEP’s OpenPDM® are available and already established in CAD/PDM integration, synchronization and collaboration scenarios

� SDM connectors are available for major SDM systems
