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
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

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 Thats it!
