1 Implementor Forums : CAx-IF and CAE-IF to accelerate interoperability solutions availability By Jean-Marc CREPEL, Associated CAE Expert, AFNeT April 19 & 20, AFNeT Standardization Days - Paris 1

2 The LOTAR project Seven LOTAR WGs Goals and Objectives LOTAR EAS WG to develop, publish and maintain standards-based mechanisms for archiving and retrieval of Engineering Analysis and Simulation information that can be read and reused throughout the product lifecycle, independent of changes in the Information Technology (IT) application environment originally used for creation. Primary Technical Approach Original Model Results Context Pedigree Recovered for review or reuse ISO STEP AP209 ed2 Multi-disciplinary analysis and design 5, 10, 15, 20, 30,, or more years April 19 & 20, AFNeT Standardization Days ParisSource Source : LOTAR EAS WG 2

3 Motivation for using Standards in CAE and other Cax domains n Interoperability for Multiphysics / Multi tools Analysis and Extended Enterprise exchanges n Long Term Archive and Retrieve n Knowledge management and Reuse Legal needs Certification Litigation Accident investigation Business needs Evaluate changes Evaluate damage Address customer questions Evaluate new conditions and mission requirements Engineer modifications Engineer derivatives Capture knowledge Exchange data An archive information package must be created to support these items, used for 2 main purposes: retrieve reuse analysis and simulation data. LOTAR supports the needs by providing an enduring data archive. April 19 & 20, AFNeT Standardization Days - Paris Source : LOTAR EAS WG 3

4 STEP AP 209 ed.2 : Multidisciplinary analysis and design n STEP AP209 is a standard for sharing, exchange and long term archiving of information between the iterative design and analysis stages of the product life cycle. n All AP242 (Managed Model Based 3D Engineering) is a subset of AP209 ed2 n Disciplines covered today by AP209 ed2 : Structural Finite Element Analysis; Computational Fluid Dynamics; Kinematics. n As a first step CAE-IF focus on Structural FE linear quasi-static Analysis using metallic and composites material types n CAE-IF initiative is expected to accelerate STEP AP209e2 processor development in CAE domain and promote usage through users community April 19 & 20, AFNeT Standardization Days - Paris 4

5 CAx Implementor Forum (CAx-IF) n Joint testing forum hosted by PDES, Inc., ProSTEP ivip, and AFNeT n Composed of CAD and CAE vendors as well as translation and validation software developers providing STEP translators n Closed group (sandbox) allowing implementors to develop and test new approaches in a trusted environment n Launched in 1999, by merging previous PDES, Inc. and ProSTEP ivip efforts. Since then, 39 test rounds have been completed focused on CAD domain. CAE domain test rounds to start on Sept,. n Mission is to meet industry s needs by developing and testing standards based interoperable products April 19 & 20, AFNeT Standardization Days - Paris 5

6 Goals of the CAx Implementor Forum Accelerate CAx translator development Ensure that users' requirements are satisfied Implement functionality for today's needs Identify functionality for tomorrow's needs Avoid roadblocks by establishing agreed upon approaches Increase user confidence by providing system and interoperability testing Ensure new functionality does not adversely impact existing implementations April 19 & 20, AFNeT Standardization Days - Paris 6

7 CAx-IF testing methodology Preparation based on: Test suite selection Test environment Rec. Practise update Translation based on: Current EXPRESS / XML Schemas Latest (draft) Recommended Practices Test Case definitions Checks performed: Syntax and Structure (conformance to schema) Semantics (conformance to Rec. Practices) Preparation phase Translate to STEP Perform STEP file checks and report findings Participants access and process STEP files; report results Participants resolve issues during the test rounds Detailed review at meeting April 19 & 20, AFNeT Standardization Days - Paris 7

8 CAx-IF Test Round Breakdown Two rounds per year: n CAD : March Sept. / Sept. March n CAE : June Dec. / Dec. - June Meeting 12 weeks Transition Meeting 6 weeks Implementation Data submission Conference Call 6 weeks Data import Results collection Conference Call 2 weeks Evaluation Preparation Meeting Meeting wrap-up (minutes etc.) Creation/Update of Recomm. Practices Preparation for test round (Test Suite, Test Environment ) Update of implementations Realization of test cases Provision of test data (STEP files and statistics) Import of submitted test data Collection of results Pre-meeting resolution of issues Evaluation of results Meeting preparation (collection of discussion topics ) April 19 & 20, AFNeT Standardization Days - Paris 8
