ESLM method for radioss optmization

Recommended Posts

Hello all !

This is my first post here, I'm a student doing my master thesis in Mechanical engineering.

Here is my issue, I successfully did the tutorial in order to realize dynamic explicit analysis with the "full car" model available in Hypermesh database  and also the " Example 51 - Optimization in RADIOSS for B-Pillar (Thickness optimization) " in order to understand how the ESL method works.

The next step is to optimize the car crash box using he ESL method, my aim is to optimize the component called " COMP-PSHELL_1 " by Thickness optimization.

I wrote the .radopt file but I encountered an issue with the .fem file.

See below the error, I was not able to solve the issue.

*** See next message about line 14864 from file: fullcarv5.fem
 *** ERROR # 1000 *** in the input data:
 Incorrect data in field # 4.

See attached the .radopt, the engine/stater file and the .fem file

Thanks for your help !

Aub N.
