I am working on Siemens NX8.5 and using the Topology optimization module.
I am looking for some theory behind the module, for example which is the method used within it. I read that most of the commercial software use the Solid Isotropic Material with Penalization, but I don't know if this is true even for NX.
Can anybody help me?
I just found today that Tosca used ESO but now it's using SIMP combined with the method of moving asymptotes. Do you know if it is correct?
