I dont know how NX display BC, but I can say that you can use two symmetry planes and constrain one node in each part in TZ direction.

Re: clarification on BC

It is not solving for that BC. if fully fixed is provided, it shown stress concentration at that node. how ever, i tried in abaqus using similar conditions where it works.
