What kind of topology optimization do you use in NX Nastran? Is there a tool available from Siemens?? I'm searching for a tool to optimize e.g. weight with the highest stiffness. I know TOSCA is available for NX.... but kind of expensive. Many thanks!
NX Nastran does not have topology optimization. Instead it is the traditional parametric gradient-based optimization with SOL 200. Here you can optimize with FE properties and some limited geometry as design variables.
In a future Femap release - likely scheduled for this year, we plan to offer topology optimization with an integrated TOSCA product. It will be priced competitively. We will also offer an integration of TOSCA in NX 8.
