Success Story

Motorcycle Crankshaft Modeling with SimLab at BMW Motorrad

Learn about the semi-automated motorcycle crankshaft modeling process at BMW Motorrad based on Altair's pre- and post-processor SimLab. The scripts developed take the FE model generation time down from 2 weeks of manual work to half a day.

Benefits:

  • 1/2 day vs. 2 weeks modeling time
  • Inhouse process now available
  • Increase flexibility
  • Consistent model quality
  • High efficient with iterations.
