contact set trouble

Hi, I am modeling polymeric window frame and doing structural simulation.  In predicting deflection under uniform pressure, global bonding option would not provide accurate result (too small deflection).  I changed to no penetration then gave me serval different error messages such as surface-based contact normal not found.  I checked out discussions on this issue but did not help me to solve my problem.  Shortly speaking, polymeric window frame has gaps between components everywhere and reinforced beams are used inside polymeric frame to reduce the total deflection of window frame.  I think global bonding option is inadequate approach to my situation as it assumes that all components touching each other would act as one.  What will be best practice to do simulation for the structure with gaps and movement inside space but no penetration?  This is very important for making decision on continuation of using Solidworks or changing FEA software companywide.  I really need your professional advice.
