Why I receive an incorrect contact force when modeling sphere to plate contact in 2d axis-simmetryc dynamic analysis in Ansys/Ls- Dyna?

Hi I am modeling contact between Sphere and plate in 2D Axi-symmetric case, using (Ansys) Ls-Dyna. I apply force (say 200 N) on the sphere, and receive contact force varying from 0 to 500 N . The...
