Dr. Wallner Group

  • 30 Persons, 10 Years Experience

  • Focus on Unigraphics, iMAN

  • Locations: Bremen

    • Wiesbaden

  • Stuttgart

  • München


  • 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


    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


    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.


    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


    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

    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!


    • 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
