Hello,
I have a problem regarding free sizing optimization with Laminates. After free sizing optimization when optistruct creates 4 plies of each fibre orientation there remain exactly the first ply of each fibre orientation which has the shape of the whole design space. In my case the 4 plies are grouped together as the first plies of my model. I attached a picture of my problem. I tried difference settings with TMANUF, min, max Laminat thickness. But the problem is always the same.
All plies based on the same elements. To introduce Loads I used RBE3 and RBE2 elements and connect them to the elements.
Do you have any suggestions how to fix my problem?
Thank you in advance
