In this paper we perform an accurate time-dependent finite-element numerical gas discharge simulation in two-dimensional semi-periodic computational geometry of the gas diode with a plane-grid cathode system. The diode configuration we investigate is similar to previously studied experimentally. Discharge simulation is performed in the framework of two-moment macroscopic (hydrodynamic) discharge plasma model accounting photoionization and autoelectronic emission from nonuniform electrodes surfaces. The results of numerical calculations can be used for further estimations of a runaway electron flows characteristics.
