A mathematical model of the electrodynamic processes in the discharge circuit and the discharge chamber of an electro hydraulic assembly is developed. In addition, the algorithm of the solution of the obtained system of equations on the base of numerical methods is proposed. The simulation of the discharge channel expansion in water is realized in a geometrically nonlinear model, but on the finite difference scheme for a stationary grid. Both the mathematical model and the algorithm developed have been tested after the example of similar problems solution a well as by the comparison with the experimental data. The influence of the finite diameter of the electrodes on transient processes in the discharge circuit and the dynamics of the discharge channel expansion have been analyzed.
