        Jake you are not missing something. The issue is: If contact boundary conditions change, it becomes a nonlinear problem (stiffness matrices change and have to be re-computed), hence linear dynamics theory ceases to apply.  The only way I know of that you can use existing SolidWorks Simulation is through the Nonlinear, dynamic option where you can have changing boundary conditions - but you will have to conduct analyses in the time domain, which may take quite a while! Hope that helps explain why you cannot put on "no-penetration" contacts in Linear Dynamics module. -Tony
