Yes. Frictional contact between the block face and shell edge will allow the block to prevent -y movement while allowing separation in the +y direction. The Z = 0 BC will prevent the edge from falling off the block in the Z direction. Another constraint prevents large movement in the X direction. Large movement is when nodes fall off the Contact surface.

If the force has a component in the -y direction then the model can solve. If the force has a +y component then the model can't solve it there is no constraint in that direction.
