Can I do simultaneous optimization for static, buckling and frequency analysis? ANSYS APDL?
for example OPTIMIZATION OF A THREE-BAR TRUSS
FINISH ! These two commands clear current data

Your suggestions and tips !?
Thanks
The answer is yes you can, I recommend to go through the thesis of Dr Diederik Veenendaa, u will find it in the linked i share

Dear Mr Bendine Kouider,
Thanks for your answer
I want to ask you about the Ansys software
Do you have a license in your laboratory?
What version
