Attached are 2 Hypermesh models. The Aim is to minimize mass. I have used 2 composite plies to model the structure. 2 PCOMPG properties have been assigned to the plies respectively. Only 1 out of these 2 plies needs to be optimized topographically to obtain stiffener patterns. The other ply must continue to remain in its original shape In the “volume_feasible.hm” file , I have minimized volume as the objective. The optimization run gives a feasible design. However, when I check the results, there is no change in the shape of the ply and no bead patterns are obtained. Next, I changed the objective to minimize mass just to see if I get the desired result. Again, I obtain a feasible design but there is no change in the shape of the ply and no bead patterns are obtained. In this model, no contact has been defined between the plies. In the “stick_contact.hm” file, I’ve defined a stick contact between the two plies and run the optimization. Here again, I obtain a feasible design but there are no bead patterns obtained in the result. if anyone has tried a similar problem before please help me out. stick_contact.hm volume_feasible.hm
