Variation of large particle size for gas discharge particles-in-cells simulation

Large particle size variation method was developed and tested for the computer simulation of pulse gas discharge inside dielectric cell via large particles-in-cells (PIC) method. Simulations were carried out with and without large particles' size variation. Comparison between these simulations' results was held for discharge current waveforms, particles' numbers, spatial locations and velocity distributions. Results agrees with each other qualitatively and, in most cases, quantitatively. The main flaw of the large particles' variation method is additional digital noise.
