  1. Ok I think I was able to fix it. I thickened up the plies until i got a displacement less than 2 mm in the analysis run. When I optimize the "oversized" laminate it reduced the ply thickness as much as possible.
  2. Hello and thank you for your quick response! When I set it to a directional displacement it states "INFEASIBLE DESIGN (AT LEAST ONE CONSTRAINT VIOLATED)" because the displacement doesn't get any smaller than ~4mm but it keeps reducing the weight instead of adding plies. I will upload the new .out file
  3. Hello, I'm currently trying to optimize the laminate of a cfk part with the free sizing optimization. At the end of the run it states "OPTIMIZATION HAS CONVERGED" "FEASIBLE DESIGN (ALL CONSTRAINTS SATISFIED)" but the programm is just reducing the mass while the displacement constantly gets bigger and is far bigger than the max displacement constraint I set for the optimization. The total displacement constraint is set to -2mm. Min ply thickness is set to 2mm and max 50mm.
