A new family of implicit-explicit finite elements partition procedures is developed. It permits different time integration methods and/or different time steps to be used simultaneously in different parts of the mesh. Critical time step estimates and the computer implementation of this technique are presented. The new method proposed herein is straightforward, and clean and has been modularized so that many existing implicit computer codes can easily be modified to accomodate the present capabilities.
