A computer simulation code at the Lawrence Livermore National Laboratory (LLNL) to predict the performance of a railgun electromagnetic accelerator has been developed and validated. The code, called MAGRAC (MAGnetic Railgun ACcelerator), models the performance of a railgun driven by a magnetic flux compression current generator (MFCG). The MAGRAC code employs a time-step solution of the nonlinear time-varying element railgun circuit to determine rail currents. From the rail currents, the projectile acceleration, velocity, and position are found. The MAGRAC code was validated through a series of eight railgun tests conducted jointly with the Los Alamos National Laboratory. The formulation of the MAGRAC railgun model is described and the predicted current waveforms compared with those obtained from full-scale experiments.
