Tolology Optimization error?!

    • Heiko Theiss

      I am trying to do a topology optimization. My static-structual data should be ok, but when I start the optimization it doesn´t advance at some point.

      The status bar just says: "optimization is being prepared:Constant data is read" (Translated).

      And if I try to stop the simulation, the program is beeing frozen.

      Does anyone know how to solve this problem? Thanks in advance

      Thanks for the quick reply.

      Sadly the is no error nor warning. It sems to work, but in reality it does not advance. I think its an error, just because I have to force close the application when I use the stop command.
