I rechecked the second example and it is a bit of a weird one so I’ll delete it and replace it with a different one. There is no force on the peak stress node, although the first node with an applied force isn’t too far away. I redid the simulation so that the forces are further away.
Yes I am using nodal forces, good point about the 182 elements, I had already tried both but there is very little difference, I’ll attach a graph where 183 and 182 elements are compared below but you can’t even see a difference: The convergence graphs are basically identical because the maximum stress is not close to the force application area.
