WIth utility "FEM-NOdes - REmove Unused nodes" it is possible to delete unused nodes.
When I select this option, I get this message:
"210 FEM entities do not exist or are still associated and cannot be deleted."
How can I delete these nodes now? I think the reason is due to deleted MPC`s in the model. Still there exists some association to old MPC`s, how can I delete unused MPC?
