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
Dipl.-Ing. Peter Binde
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
Dipl.-Ing. Peter Binde
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.
Dipl.-Ing. Peter Binde
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
Dipl.-Ing. Peter Binde
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!
