I'm having difficulty getting a contact to work. The initial gap between the 2 contact surfaces is 0.2". Using Sol101. The picture attached shows a bar attached to a dummy shell thru RBE2. The picture shows only 1%
of the whole model. The idea behind this model is let the pin move 0.2" before it starts reacting any load. The checked the normals, surfaces, max search dir, switched master/slave etc, but nothing worked. H
Plot element normals, to develop contact the region´s element normals should point one againts the other, this is a common error. NX NASTRAN creates a contact element if any of the source element normals intersect with an element in the target region.
If not arrived to a valid solution, post your FEMAP model here and we can take a look to it, OK?.
