Volkswagen's Needs for Future FE Modell Creation Strategies
for NVH and Crash Applications
Dr. Volker Schulze; Dr. Jürgen Bruns, Volkswagen
Group
The increasing model range and the reduction of the development
cycle times are resulting in higher demands
on the simulation techniques. Based on the knowledge of the
developments in
the model generation process during the last
decade, an idea of future demands in this field was developed.
Generally speaking
these are the topics of model quality improvement,
handling of meta-information and model structuring: First,
the solver
should deliver a readable summary of the input
data. Second, non-geometric information has to be conveyed
from the CAD-documents
to the final post-processing operations. Third,
a modular approach has to be established in the model generation
process,
ensuring both fast model changes and reliable
simulation results. These requirements are prioritized with
respect to the necessary
software development steps.
