description: Using numerical simulation of current spreading in the ground using finite element implemented in the software environment Comsol Multiphisics considered a series of tasks to determine the effect of the geometry of the electrode earth electrode, soil strength parameters, model geometry and calculation region on the main characteristics of memory. It is shown that the calculated characteristics of the SD impedance have a frequency dependence. Improving the quality of calculations associated with the transition to the solution of the current spreading problem in 3D formulation, showed that the behavior of the current observed from the calculated data when a lightning pulse of voltage is applied to the battery in the form of a rod electrode can be described qualitatively by the reaction of a 3-contour substitution scheme containing R, L, C elements. Comparison of the results of calculations performed using different grid scaling in the zone of high parameter gradients near the ground electrode revealed a weak influence of the grid scale on the parameters and shape of the current flowing through the boundaries of the calculated area. This observation allows us to make a preliminary conclusion about the possibility of reducing the required computing resources for the calculation of the memory in cases when local processes in the zone closest to the memory electrode can be ignored.
