Currently I am just using set_all_boundary_ids and set_manifold_id to identify
the nodes around the hole. Is there a way to specify the equivalent node (the
node in the middle related to the constrained nodes) in each hole and apply
the boundary conditions directly in this node?
That's the wrong way to see it. Mathematically, you're applying loads to
faces, not individual nodes. You should set the boundary_id of the faces on
which you're trying to apply a load to a different value than the other faces.
You can then use VectorTools::interpolate_boundary_value with that particular
boundary_id to evaluate the load you want to apply.
Is it also possible to read the equivalent node from the *inp file?
I think I don't quite know what you mean by the "equivalent node". Do you mean
the center point of the hole? That's not a part of the mesh, so it's not
usually mentioned in the .inp file.
