FRF Correlation in Hyperstudy
Hi guys,
I'm trying to do a FRF correlatiom in Hyperstudy. I have the model in Optistruct (it's a simple metal plate) and I want to adjust the model so the FRF curve fits the experimental results.
I have successfully input the data in Hyperstudy (the curves from .h3d from the simulation and the .csv from the experimental analysis) in the data source tab and I've created another data source of area between the two curves. Then, in the respose tab, I have selected the max(area) with the minimize objetive (as is in the tutorial).
However the area is negative?? And when I try to run an optimization, the response doesn't change when the parameters change. What am I doing wrong?
For the parameters i have density, young modulus, poisson and material damping.
