      Setting up numerical computations of an explosive-magnetic system used in electrophysical experiments in high energy density physics (liner experiments, pulsed thermonuclear fusion, etc.) is described. Governing equations and boundary conditions are given which model operation of the disk electromagnetic generator, the electro-exploded foil fuze opening switch, the liner ponderomotive unit and the transmission lines connecting system elements. A scheme is given for consistent solution of these equations implemented in a program complex for numerical computations on SVS type computers.
      Detailed accounting for the design of the system under consideration, the mode of its operation and using, as a rule, general physical characteristics of materials used such as equations of state, conductivity etc., are suggested. The technique allows to predict temporal dependencies of currents, voltages and other system characteristics within the accuracy order of these charac-teristics measured in the experiments.
