Thank you for answer I'm trying to move the node of the truss. In the picture it's the node with the force. Is there posibility to do optimization like this to minimize stress in the rodes moving one node of the truss?
Hello, I am new to Optistruct and having a repeating error for my 1D linear static free shape optimization of truss. When I try to run it w/Optistruct, the error that I get is: *** ERROR # 7315 *** No DSHAPE grids are on the boundary. Any ideas about a possible reason for this error? I checked card of DSHAPE and everything looks ok. Thanks, kosa26
