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?
