Good morning, I'd like to share a bit about my situation.
Recently, I performed a free-size optimization on a laminate under a static load case (application of constant pressure), using mass as the objective function to minimize and applying a Tsai-Hill maximum value of 1 as a constraint (this limit must not be exceeded). My model converged correctly after 25 iterations.
Now, I need the sensitivity of the responses—not only for mass but also for Tsai-Hill—which means I have to run the optimization again. To simplify the calculation, I set DOPTPRM,DESMAX,6, since after the 6th iteration the model barely changes, so this number of iterations should be representative enough for a good sensitivity analysis.
I then requested OUTPUT,H3DTOPOL,ALL in the output options to get the sensitivities of all structural responses I defined (including Tsai-Hill, defined via DRESP1), but I'm only getting the sensitivity of the mass. I also tried OUTPUT,H3DSENS,USER,BYITER to see if I could finally get the derivative of the Tsai-Hill response with respect to the thickness of each layer, but still no success.
Do you have any ideas or suggestions?
Best regards.
