This tutorial demonstrates how to use the DMAP alter to create MPC equations that sum interface forces.  It uses a simple model of two plates connected at four locations.  The tutorial uses FEMAP to help generate inputs for the alter and MATLAB with IMAT to convert the DMIG results into MPC cards.  Finally, the tutorial shows how to use unit loads to check the MPC equations.
