Hello Amit I liked 's suggestion to do 1/4 symmetry on the silicon chip. That leaves a single DOF that is taken care of by frictional contact between the chip and the base with the spherical dish and the chip and the sphere. I agree that the silicon chip should be shell elements meshed on a square surface. I agree that the sphere and base should be rigid bodies. Note that only the silicon chip can have symmetry boundary conditions, the rigid bodies don't get that treatment. That model should solve without too much difficulty. Attach a .wbpz file and I will help get that model working.
