The physical model of a two-dimensional three-temperature radiation magneto-hydrodynamics code, named MARED, is introduced. The code’s 1 D simulation results are also presented, which include results for different currents and load parameters on facilities of Saturn and Qiangguang-Ⅰ. The plasma parameters’ spatio-temporal distributions are obtained, and their self-consistent dynamic variations suggest that MARED code applies to simulations on different pulse power facilities and load conditions. By comparing results with different load materials, it is found that X-ray power of tungsten wire-array implosion is greater than that of aluminium wire-array for the same load mass. In addition, MARED simulations also show that the calculated X-ray power goes up with the load current, and goes
