Introduction Methods to manage CAD data and processes (PDM) are well understood today across the industry Consequently, is now being applied for simulation and test adopting PDM systems to the requirements of the analysis domain implementing simulation data management (SDM) tools Horizontal coexistence of data management tools in different domains raises questions not addressed so far data ownership, dependency, traceability Surveys such as done by the NAFEMS led FENet project show the various integration aspects of engineering analysis into the development process as high ranking technology issues with still only medium availability across the industry NN 21/09/07 Seite/Page 3

High Priority Issues in the CAD/CAE Integration Domain (as identified by FENet) Integration of tools for structural analysis and life cycle analysis geometry, loads, material property p databases, Integration of engineering analysis into design and development processes more effective development processes cycles support of collaborative, concurrent, multi-disciplinary engineering Use of legacy models and data Need for better data integrity, open standards, configuration control, metadata CAE-to-CAD modification feedback Use of open standards STEP, W3C/XML, OMG, http://www.fe-net.org/ NN 21/09/07 Seite/Page 4

Application and Integration of Digital Simulation Software today Application of CAE today includes initial design, simulation, verification, certification, etc. with increasing tendency including static, (fatigue) strength, and vibration analysis, CFD, dynamic systems, plastic deformations (crash),... systems engineering, CAD, CAE, CAT, CAM MDO, multi physics However... there is no common (data-/reference-) base for the various digital simulation tools can PDM for CAE data not simply be adopted from CAD without considering the simulation specifics does a coupling between CAD and CAE virtually not exist is lifecycle management for CAE data as well as interrelations between CAD and CAE therefore simply an illusion i today NN 21/09/07 Seite/Page 6

The 4 Challenges of Simulation Data Management Maintain product context for CAE information? Time Make CAE MS information referable?? MS Design MS Simulation? MS Keep inter-relations of CAE information with other domains CAD CAD PDM Vault CAD CAD CAD CAE Information Manage CAE information during the product lifecycle NN 21/09/07 Seite/Page 9

Keep inter-relations of CAE information with other domains Close interrelation exists by nature between information in product design and simulation subject of CAE activities is the verification of 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 respective activities in the other dependent d domain typically iterative processes, often with feedback loops These interrelations even though logically existing cannot be represented persistently today 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 part level relationships between CAD and CAE therefore span granularity levels today no way to represent the creation processes of CAE information (engineering intent) NN 21/09/07 Seite/Page 10

OMG Model Driven Architecture Computation Independent Model (CIM) Platform Independent Model (PIM) Platform Specific Model (PSM) Platform Specific Model (PSM) Implementation Implementation CIM -A computation independent model is a view of a system from the computation independent viewpoint. A CIM is sometimes called a domain model or a business model and a vocabulary that is familiar to the practitioners of the domain in question is used in its specification. PIM -A platform independent model is a view of a system from the platform independent viewpoint. A PIM exhibits a specified degree of platform independence so as to be suitable for use with a number of different platforms of similar type. PSM - A platform specific model is a view of a system from the platform specific viewpoint. i A PSM combines the specifications in the PIM with the details that specify how that system uses a particular type of platform.
