Abstract:

This report documents enhancements made to the EPIC2 post-processor and the implementation of color into the post-processor. Reference 1 describes the EPIC-2 program and contains a users manual for the program and post-processor. This report can be utilized as documentation for the original EPIC-2 post-processor, STPLOTPL, by merely neglecting the information pertaining to color graphics. Plotting information for the post-processor is written on two tapes by the EPIC-2 program at user-specified intervals. One tape contains all the flow field variables at preselected times. The other contains time histories of flow field variables at preselected times and locations. EPIC-2 is a two-dimensional computer program for impact and explosive detonation problems. The capability to treat spinning projectiles is also included. The numerical technique is based on a Lagrangian finite element formulation in which the equations of motion are integrated directly rather than through the traditional stiffness matrix approach. Trilinear material strength compressibility effects are included to account for elastic plastic flow and wave propagation. Additional keywords Modification Subroutines Instructions.
