Results of HEMP code calculations of simple problems are compared with exact results to determine the accuracy with which this numerical technique solves initial-boundary value problems. More complicated problems of metal liners accelerated by explosives were also calculated with this code, and these results were compared with experimental results to determine how well the code simulates these physical processes. It is concluded that HEMP calculations are accurate enough to be useful as a tool for predicting the gross motion of metals accelerated by detonating explosives.
