  1. PDM Integration of FEA Design processes • iMAN and DesignSpace – • CADFEM Usermeeting 2002 • Peter Binde

  2. Content - Dr. Wallner Group - iMAN, DesignSpace and Unigraphics - Why Integrating FEA in PDM - Requirements for the Integration - UG Concept of Master Model - Variants for DesignSpace iMAN Data model - How to Implement - How it looks like

  3. Dr. Wallner Group Consulting and Service around CAD, CAE, PDM Competences: - Process-analyses and -syntheses - Trainings and workshops - User-support and hotline - FEA / MKS analysis and design - Integration-solutions and software-development

  4. Dr. Wallner Group • 30 Persons, 10 Years Experience • Focus on Unigraphics, iMAN • Locations: Bremen • Wiesbaden • Stuttgart • München

  5. iMAN, DesignSpace and Unigraphics • Present Situation: • More and more FEA becomes the designers daily work • PDM is established for CAD Applications • iMAN/Unigraphics products and DesignSpace are from different companies, ... • Questions: • - Integration? • Will there be an interface? • Will it be supported? • This Article: • Shows a way to encapsulate DesignSpace in iMAN. • Demonstrates processes for CAD/FEM integrated in PDM

  6. Why Integrating FEA in PDM Improve Communication and Data-Retrieval: - Better security of data - Better data exchange - Data-retrieval from different users, departments, locations - Restrictions possible - Data is always up to date - Integration / Comparison of FEA and prototype-testing Improve Documentation: - Documentation of A-B changes - Easier selection of „Carry-Over“ parts - Documentation for quality-insurance needs

  7. Why Integrating FEA in PDM Use of digital Workflow Support: - Prove, release, change processes Reusage of FE Data: - Use of FE-data for knowledge reuse - Digital-Mock-Up using FE-data: Reusing meshes or the stiffness of piece parts in FEA or MKS for assemblies.

  8. Requirements for the Integration Keep DesignSpace / UG native possibilities: - Associativity to CAD geometry, parameter-transfer - Transfer of attributes from CAD to FEM (Ex. Shell thickness) - Transfer of weld point-info from CAD to FEM - Keep normal usage (starting DesignSpace from UG) Integrate Geometry Preparation: - Provide all CAD methods to prepare the geometry - Do not change the original part

  9. Requirements for the Integration Other Requirements: - Provide overriding of CAD geometry-parameters (For optimisation of different parameters) - Organize the DesignSpace report - Provide export and import of all related data from the database

  10. Operating-System File Drawing Kinematics Strength ... Assembly Drawing ... CAM Strength Component Component UG Concept of Master Model Data Structure Outside Database (Native):

  11. Dataset Object, includes Attributes and several Files: Drawing Kinematics Strength ... iMAN Dataset UG (.prt) References: Assembly Ansys(.db) Attributes, Methods Word-Doc (.doc) Drawing ... CAM Strength ... (*.*) Component Component UG Concept of Master Model Data Structure in iMAN Database:

  13.

  14. How to Implement 1. Create a new dataset type or modify one of the existing - Insert as reference: UG (*.prt) - Insert as reference: DesignSpace (*.dsdb) 2. Create a new tool - Let the new tool start DesignSpace - Let the tool work on the new dataset type That‘s it!

  15. How it looks like • Item-ID and Item-Name • Revision (A) • Folder for FEM Datasets • New FEM Dataset: • Can be opened by: • - UG: For Geom. Prep • DesignSpace: FEM • Original Geometry • Dataset
