Periodic boundary conditions

Recommended Posts

Hi,

 

I want to simulate the elastic (and further the elasto-plastic) behaviour of arbitrary lattice structures with hyperworks by the use of unit cells.

Is there a possibility to apply periodic boundary conditions to simulate unit cells? 

 

In addition to that i've tried the Multi-Scale Designer for a simulation like this but there is a major limitation. Within MDS i've to specify matrix and the fiber material but i'm only interested in the behaviour of the fiber material without any influence of the matrix material.

 

I hope someone have a solution regarding this topic ;-)

best regards

Hi @awal

 

For which solver are you modelling for?

 

If you are modelling for OptiStruct you can use PERBC to modelling periodic boundary conditions. For more information please refer to PERBC section on OptiStruct help.

Thy for your reply,

 

This is a very helpful information. I will try it with my structure.

 

PS: I want to solve this problem with the optistruct solver. 

 

best regards
