Stiffness to Compliance

Altair Forum User

Hello,

 

I want to perform a topological optimization of a part to minimize its mass, with a given constraint on the compression stiffness along a single direction. I’ve tried to turn this stiffness constraint into a compliance constraint, without results.

 

My questions are :

Is there a way to create a constraint on a compression stiffness along a single direction ?

If not, how can I turn correctly this compression stiffness along a single direction into a compliance constraint ?

 

Thanks

use compliance response and it is a global response and do not depend on directions.
