setting Compliance constraint

Hi,

I have to run a topology optimisation on a simple structure, a kind of fixed-end beam with some loads applied . Known the maximum displacement I want to have, how can I perform a calculation of the compliance so that i can put it as upper bound in DCONSTRAINT settings?

Thanks to anybody will answer

Hi Vale,

Why not have displacement constraint instead?

First of all, thanks for your answer.

I have tried before to run an optimisation with MIN MASS as objective and Maximum DISPL as constraint but it doesn't work. So I have decided to try another way.

Hi ,

Please have a look at commonly used & suggsted topology optimization formulation.See attached screen shot from Optstruct FAQ.

Hi,

You can use regional compliance as constraints too. Give a try.
