Delete elements based on external calculation

Rahul_P1

Hi

I would like to implement a methode in Optisruct (hypermesh version 11) who can delete elements on my own methode. The methode shuld calculate utilization by FKM.

It is impossible and has anywhere a idear how I can do this ?

Hello,

functions from external routines can be used in OptiStruct by using the DRESP3 Keyword and programming in HyperMath, C or Fortran. The general procedure is described in the OptiStruct help, chapters:
- External Responses
- DRESP3

There also is a tutorial describing the way to include external responses in OptiStruct (for size optimization instead of topology, but the procedure should be the same):
- OS-4095: Size Optimization using External Responses (DRESP3) through HyperMath

The described way through HyperMath should be the easiest, as no compilation of the script is needed.

Kind Regards
Jan
