Surface load pressure disappears after contact

Hi

Im using Abaqus Explicit. My model includes a rigid body that contacts and indents into a deformable body. Before the contact happens I applied a pressure load on the contact surface of the deformable body at the first step. In the second step I moved the rigid body toward the deformable body so contact happens. My problem is the surface elements at the beginning of this second step are in equilibrium with the pressure load that I have applied but when I move away the rigid body from the deformable elements (you may see it as unloading), their pressure values would become around zero as if the surface pressure has never existed! Is there something Im missing here? I would appreciate if anyone gives me some hint in case they have already faced such situation.

Thanks

Fred

That sounds strange. Are you sure that the surface pressure is still active at that time in the FE simulation?
