Executive Summary

Authored by John J. Watrous and Michael H. Frese of NumerEx for Los Alamos National Laboratory in 1993, this report details the integration of a dynamic explosive model into the MACH2 magnetohydrodynamic code. The model enables the simulation of explosive magnetic flux compression generators by capturing the essential qualitative behaviors of detonation waves and their effects on conducting armatures. The document provides validation through one-dimensional and two-dimensional demonstrations, highlighting the code's utility for designing pulsed-power devices.
