DOE and Optimisation
Hello, I'm trying to run an optimisation within a DOE under Hyperstudy/Hypermesh. Initially I've tried running the optimisation inside the DOE tool under Hypermesh but that was giving me way too many runs (I believe it was creating a run for each iteration of my variable, which was not exactly what I wanted) I ran an…
