Lattice structure with stress constraint

Hello

 

I tried to optimize a modell with a lattice structure. This model needs to fullfill a  certain stress constraint. 

The lattice structure is created, but the stress constraint did not implement properly. The full volume does it stick to the stress constraint, but the lattice structure itself does not and achieve too high stresses.

 

What can be done, that the stress constraint is also taken account of the lattice structure.

 

I aded following line to the .fem file:

+       LATTICE 1       0.1       0.7       10.

 

I thank you in advance for your help!

    Hi,

     

    Did you provide any stress constraint?

     

    Can you share the model file through file transfer link?
