Contact Options

Hello everybody.
After the Solidworks Simulation Training I am trying to step intothe Contact Analysis a little deeper. I am referring to the fileattached.
I have a pliers which squeezes a flat stock. During the traininglesson the teacher said we are not interested in the contactstresses that develop between the arm and the hinge pin, nor we areinterested in the contact stresses between the arms and the pieceof flat stock.
Well this is exactly what I am trying to do. If I set contactbetween components and I run the analysis nothing appears on theflat stock.
I have tried many options but no results.
Could someone help me? Thank you
