We describe a new 3-D computer code, named MESA, developed at the Los Alamos National Laboratory with DARPA/Army/Marine Corps support specifically for simulations of armor and anti-armor systems. MESA is a three-dimensional, cartesian, Eulerian code with hydrodynamics, high explosives, and material strength models. Among special features of MESA are its high-order advection algorithm, its material interface tracking scheme and the van Leer monotonic advection limiting. We will briefly illustrate the code capabilities by showing comparisons of two calculations with experiments. The first problem shown in this paper is the impact of a lead sphere on a thin lead plate at 6.66 km/s, producing a debris cloud composed mostly of vapor. The second problem is the impact of a copper cylinder at 130 m/s on a rigid wall, producing deformation in the cylinder. 17 refs., 5 figs.
