    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
