    Hello again, Here is an updated model and example optimization. Find attached the model file. The example is a topology optimization (objective: max. stiffness, % of space volume). Best Regards, Mario model0817_CleanUp.stmod

    Hello, I would consider the following things: The constraints and force are not connected to the solids (non design), since they are attached to free points. This will be the reason for the error message. All longitudinal and vertical inner beams are modeled twice There are a lot of intersections and so it is a problem to find clear contacts for the solver. You get a warning message before the run (in my version 2017.3) At all, try to model a flat solid plate between the two non design borders. Then you get a idea on how a optimized support structure looks. After clean up point 1 and 2, I could do a structural analysis (see attached picture). I did not try to perform an optimization, since it is useless for me. Best Regards, Mario

    Hi Ffog, With Inspire 2017.3 the Lattice optimization will allow you to compare different performances for a Topology Optimization and Lattice Designs. At this moment, export is not supportet. If you are an advanced user, you might use Altair Optistruct and Altair Hypermesh to do further investitations for Lattices. Kind Regards, Felix
