Abstract

The numerical algorithm for investigation of plasma cooling and decay after capillary discharge is described.The axially symmetric hydrodynamic model is considered.The set of hydrodynamic equations in partial derivatives is discretized and changed by set of ordinary temporal differential equations that is solved numerically.The analytical fitting to calculate spatial derivatives is used.The main spatial regions that are problem for numerical simulation are pointed out and analyzed.The way to avoid numerical problem near the capillary axis center and capillary wall boundary is presented and analyzed.
