I am modelling the compression of an auxetic lattice structure between 2 steel plates. The model is made of 3 bodies. The issue i am having is that the members of the lattice body are penetrating one another, i think this is preventing the force/displacment graph from showing non-linear properties. Can anyone tell me how i can prevent this. 

many thanks,

Under the Connections folder

Add Frictional Contact between the faces that are penetrating one another.

Add a Contact Tool to check the Initial Contact Status.  If the status is Far Open, edit the contact and type in a Pinball Radius large enough so that the Initial Contact Status is Near Open.
