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

slide4

Dr. Wallner Group

  • 30 Persons, 10 Years Experience
  • Focus on Unigraphics, iMAN
  • Locations: Bremen
          • Wiesbaden
  • Stuttgart
  • München
slide5

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
slide6

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

slide7

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.

slide8

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

slide9

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
  • Dataset
