Hi everyone,
I am currently working on a non-linear shape optimization in Optistruct. I wanted to ask briefly if anyone has guide, introduction or tips for me to learn this non-linearity in Optistruct better. Until now I have always done it linear and I have come up with many questions.
I already know the theory of non-linearity but how to apply it in the softwar I don't know.
I thank you for any tips and advice.
