I have created a beam model that consists of cocentric beams that are in frictional contact with each other. The beam-beam detection setting is “Internal Pipe Contact” and the pinball radius is set to be slightly larger than the outer tube inner diameter. There is considerable clearance between the beams.  <\/span><\/p>\n

When I use the contact tool to make sure that all of my contacts are properly set up, I see that the gap and geometric gap calculated is not at all what it should be. <\/span><\/p>\n

The outer beam has a CTUBE cross section. Originally my inner beam had a user defined cross section. To test out the contact tool I changed it to a circular section(CSOLID) with an outer diamteter that envelopes the original section. The geometric gap is still not correct. <\/span><\/p>\n

I think what I am doing is straightforward and I do not understand what I could be missing. Could this be a bug in the system? FYI, the geometry was created in Spaceclaim. <\/span><\/p>\n
