Lattice optimization

Altair Forum User

Hello everybody, I'm trying to do a simple lattice optimization of a cube. I ran the optimization and everything was fine but in Hypermesh I don't see the lattice. There is the topology optimization but it seems a solid and not a reticular shape. How can I see it? I tried to export in STL but the result doesn't change.

Hi @Gabriele Porceclli

 

After optimization, OptiStruct automatically writes out a <filename>_lattice.fem file in the working directory.

 

Can you import that file and check if you there is any lattice generated?
