Hey Sean,

I flipped between target and contact (now contact is the plate edge) and with this change the results already changed a lot:

Deformation plot:

Stress plot on the plate, first load substep:

Stress on both bodies, final:

Number Contacting for the contact side (plate):

The contact between bodies seems to be better resolved now, but not completely. I cannot understand why no stress was calculated in the sphere. Also, I tried solving again for force instead of displacement, and got the same error as initialy.

Any more ideas? :)
