How can I cut running time for an analysis with no pen BC?  My model has a fiberglass beam and a cable bar inside to reinforce its bending stiffness.  A cable bar is constrained in its movement by three vinyl blocks that fill the cavity of the fiberglass.  They are not bonded so I need to use no pen BC. Also, there is a significant difference in solution (central deflection) between bonding BC and no pen BC.  The latter predicts more accurate solution. Should I set up all interfaces using local contact set up to speed up the analysis?

Thanks,
