Hello,
I am a new user of the Topology Optimization NX Nastran (version 12.0).
I did the Siemens tutorials and tried to reproduce the same steps for another geometry that I created. However, the optimized geometry's displacement is way too high. It results in 25 mm, although I set a constraint for it to be not hight than 3 mm.
Also the material density results make no sense: if I use a Lower Bound equivalent to 0.04 some random meshes (which are not even connected) appear; if I set the lower bound to 0.03, the whole geometry appears.
Does anyone know what is happening?
Thanks!
