Solid under 0.25psi uniformly distribued pressure on the whole area

This is 20"x20"X0.1"(thick) steel plate with fixed supported boundary conditions. It has different level of meshing to test the convergence using Microstruct.Prime, STAAD Pro and SAP2000. The plate is subjected to 0.25psi uniformly distribued pressure on the whole area. The result is listed below.

E = 30000 ksi

Position Ratio = 0.3
