Beam pre-tension direction problem

      Hello,

      In my analysis model, two plate and a fastener exists (as a beam). When I apply bolt pre-tension to the beam element, plates are seperating. However, it should squize the plates. I thought that it might be a visual problem because when i checked with the contact tool, the contact seems appropriate.

       

      Edit:

      I checked with bolt pretension probe, and adjusment reaction (mm) has a minus sign. 

      Any suggestions ? 

      Thanks in advance

      Also the beam connection can be used
