NX can take polygon bodies as entries for Simulation Object Structural
Deactivation Set, but the results do not show that the selected area related
to the polygon bodies are left out of the calculation.
Solution
Looking inside the *.diag, we can see a warning message that the simulation
object Simulation Object Structural Deactivation Set is being skipped:
WARNING : Skipping load and constraint set DeactivationSetBodies
This is because the nodes/elements are associated to the polygon faces and not
to the polygon bodies.
Choosing the polygon faces instead of the polygon bodies will correct this.
Or, choosing directly the nodes/elements.
