The bottom surface of the base plate is constrained in all directions. A pressure load is applied to the upper surface of the cover plate after preloading the bolt.
In the first load step, pretension loading of 2544690 N is applied to the pretension section through the SLOAD command.

In the second load step, a pressure load of 50 MPa (which is less than the equivalent pretension load) is applied to the upper surface of the cover plate.
