How do to parameter optimization in OptiStruct?
Hi,
I have a simple Geometry, and the material of this Geometry is a Non-Linear material model. In this model the input load is the displacement and the output is the reaction force. I want to optimize the parameters of this Non-Linear material model, so that the reaction forces matches to the measurements.
Can someone suggest how to do this optimization.

Are you familiar to HyperStudy?
There's a tutorial for material calibration with Radioss, but it's the same idea.
