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.
