AP209 Enables Analysis Feedback to Design • The original Part1 and it’s nominal design shape (NDS1) for a point of reference (node to hook into PDM) • Part1_Version2, the final Analysis_Version2 (FEM3) and the idealized analysis shape that reflects the performance requirement changes (IAS3) • The analysis report containing the rationale documenting the design changes (modes/frequencies, stiffener buckling, model idealization and tuning process) Part1_Version1 Analysis2 Analysis_Design_ Version_Relationship1 Analysis2_Version2 Part1 NDS1 Cross-Section Shape Representation FEM3 Analysis Report Representation Part1_Version2 IAS3

10. Integration of Design and Analysis Information in a PDM is a Powerful Systems Integration Approach • ISO 10303-209 provides a standardized meta-model for the implementation of PDM Design - Analysis data management • PDM Customization straight-forward • Automation of a PDM - managed Design - Analysis cycle furthers the goal of truly integrated systems • AP209 provides a standardized capability to share information between Design and Analysis disciplines
