  The boundary conditions are not a concern and can be used/simulated. You only need to account for the rigid body motion. In Static structural, you are solving [K]{u}={f}, whereas in an explicit analysis since the time frame is small you solve the full equations of motion, i.e., [M]{a}+C{v}+[K]{u}={f}. i.e., you are accounting for the inertial effects.

  In the examples that peter provided, other community members have analyzed it in static structural.
