1 Simulation Data Management with Interoperability across domains Matthias Grau PROSTEP PROSTEP AG Dolivostraße Darmstadt PROSTEP AG 2007

2 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 2

3 Enterprise Application Integration for Technical Product Data Current Situation Methods to manage data and processes (PDM) are well established in today's industries Location Org C Org B Org A X Y Z x System x Org B Y Org C X Information Org A Z Meta information exchanged between PDM systems, but always remains within the design domain scope stays unchanged One major type of design tool: the system high information content overlap Engineering Scope 3

4 Enterprise Application Integration for Technical Product Data A new Situation The use of different data management tools across domains creates challenges regarding (e.g. data ownership, dependency, traceability) Location Common Product Information Org C Org B Org A Z 1 x Simulation Tool x 5 Engineering Simulation Testing Product Information A complete new level of complexity! Engineering Simulation Testing Engineering Scope 4

5 Top Issues in the /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- modification feedback 5

6 The 4 Challenges of Simulation Data Management Maintain product context for CAE information? Time Make CAE MS information referable?? T i m e MS Simulation? MS MS Keep inter-relations of CAE information with other domains PDM Vault CAE Information Manage CAE information during the product lifecycle 6

7 Keep inter-relations of CAE information with 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 and CAE data analysis relevant aspects often not visible at the part level relationships between and CAE need to cross levels of granularity today there is no solution to represent the creation processes of CAE information (engineering intent) 7

8 Integration of CAE with other Domains Engineering Simulation Common Product Information Manufacturing Domain integration at PDM level: dependencies change management Product Information Simulation CAE Information Vault Loads Materials CAE Data Cluster CAE Data Cluster CAE Data Cluster Domain integration at CAE data level: information context engineering intent 8

9 Enterprise Scalability requirements Indicate using an integration platform Typical custom developed point-to-point connectors are Unmanageable PDM A A standards based integration platform allows Enterprise Scalability n (n-1) = 20 2 n = 10 PDM A ERP E PDM B vs. ERP E Standard Interface PDM B CAE D C CAE D C Exchange of information without standard interface Exchange of information with a standard interface 9

22 Summary CAE is increasingly used in the product development process, therefore data management and integration becomes more and more significant The integration of and CAE leads to a new and often underestimated level of complexity Heterogeneous environments as the CAE world clearly is - demand vendorindependent, 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 /PDM integration, synchronization and collaboration scenarios SDM connectors are available for major SDM systems 22
