Recent improvements to MACH2 and MACH3 for fast Z-pinch modeling

Summary form only given, as follows. The U.S. Air Force Research Laboratory's 2 1/2 and 3-dimensional magnetohydrodynamic simulation codes, MACH2 and MACH3, are used by many laboratories to simulate fast Z-pinch experiments. In this talk we will describe numerous improvements made recently in those codes specifically related to modeling those experiments, and show the improvements that result in the simulations.
