    Running a Non-Linear Study on Viscoelastic Material

      Hello, I'm just looking for some advice on what improvements I can make to my model to get the results I'm looking for. We're modeling the compression of a themal pad under a normal load and we'd like to see the resultant deformation and stress distribution on the pad after compression. In order to model the displacement we had to come up with a fixture that would not hold the thermal pad in place, so we've sandwiched it between two aluminum plates in the model. I'm using a no-penetration contact with node-to-node contact types and the solution won't even get past the first step - it just freezes while calculating the number of contact points. What am i doing wrong? Is there a better way to restrain the thermal pad? Any help would be appreciated. I've attached my setup and a screencap of the problem.
