For checking equilibrium condition, it is UNNECESSARY to extract the
internal forces. A good postprocessor can do that for you.

If you only check static equilibrium, you are still driving at night without
headlights. You need to check compatibility condition, too. A good
postprocessor can check equilibrium & compatibility condition, and can check
the accuracy of eigen-solution.
