We propose a complete relaxation magnetohydrodynamic (MHD) model for the simulation of electromagnetically driven high energy density (HED) systems. The full relaxation MHD model is composed of relaxation electromagnetic wave, relaxation heat transport, P1/3 approximate radiation transport and certainly the indispensable hydrodynamics (HD). The electromagnetic part transitions from electromagnetic propagation in vacuum to magnetic diffusion in plasma in a natural way. The phase and group velocities are finite for this relaxation system. Therefore, the relaxation MHD can degenerate to resistive MHD and is convenient for explicit parallel computations. The FOI-PERFECT code is developed, based on the relaxation MHD. The key numerical techniques and various applications are given.
