While trying to come up with a way of generating random FEA problems and running topological optimization on them, I ran into a strange issue. Sometimes, judging by the von Mises field, the 2 loads applied seem to have swapped their positions (see figure below). And less frequently the von Mises field doesn't seem to be related to the initial FEA problem at all.
