Issues with Modeling Rigid Probe Micromotion in Soft Tissue

I am an undergraduate student working with COMSOL for the first time this summer. I am trying to model the effect of a rigid body moving relative to soft tissue. I designated a prescribed displacement for one surface of the rigid body. My output graph displays stress in the rigid body as a result of the rigid body's contact with the soft tissue during movement. However, the output graph shows stress in the soft tissue to be 0.0 at all points, which doesn't make sense considering its contact with the rigid body.
I know there must be some issue with my model, but I am not sure how to get the tissue included in the analysis. Any advice on this issue would be greatly appreciated! I have attached my .mph file.
