Hy there,
i'm setting up a composite optimization in Hyperworks (Solver: Optistruct) and want to use the displacement of a few nodes (measuring Points) as Responses. Every node has its own coordinate System, in which i want to measure the displacement (for example in x-direction). This is caused by the real displacement and measuring directions of the manufactured (existing) part.
The displacements of this nodes should be in a specific range (constraint) in the optimization. This ist how i want to define the stiffness of my model.
I created the Systems (by global coordinates, vectors and nodes) and assigned them to the measuring points ( mesh -> assign -> node Analysis System).
Afterwards i created the corresponding responses of the same nodes (analysis -> optimization -> Responses -> static displacement) and gave them their constraints.
I did set up a freesize optimization and all Response values in the .out file are zero (except Mass).
Which approach would you suggest for my Problem?
Thanks in advance,
Andreas Kießkalt
