  1. Hello, I am in need of help setting up an Optistruct run. I want to optimize wall thickness with a upper limit on stress. I have used a 2D automesh and I have a DTPL that veries wall thickness of the main body a base of 1.0mm to 10mm (defined by material property). I have the objective of the Optimization to Minimize VolFrac, and the responses set to VolFrac and StaticStress. Lastly I have set the upper bound of StaticStress to be the Failure stress with a OptimizationConstraint. Whenever I run the Optimization the wall thickness does not very with every iteration (stays at 1.0mm). Attached is my .hm model. Is there a tutorial that shows you how to do this? Thanks!
