I haven't been following this thread very closely so I might be sucking air as far as your actual question is concerned; never the less there may be a solution to your problem.
If you're trying to simulate a compression only contact and your program doesn't do it directly you can do two separate runs. Model your structure as two separate structures (or not, it doesn't matter if there are other connection points than the one being considered) providing short links with hinges on both ends connecting the structures. Do two runs, one with the links active and one with the links inactive. If you're using the program to do the actual design you may also have to make some load cases inactive to avoid erroneous solutions.
If you have an actual gap you can still accommodate it. artificially shorten the link member by some way (such as using a very low temperature; but there may be other ways such as fabrication error if the program accommodates that).
Just some thoughts. Throw them out if they are not useful.
