Abstract

Features of optimization of the program block in mechanics and electrodynamics problems of background plasmas on an example of a problem of a flow of the cylinder placed in a stream of low-ionized dense plasma are considered. The choice of an optimum step on time, the size of settlement area, a settlement grid, feature of a choice optimum certainly-raznostnyh and numerically-analytical methods of calculation is discussed. The special attention is given to possibility of application classical stability conditions of Kuranta-Fridrihsa-Levi to problems of the given class.

Keywords:

background plasmas; the indissolubility equations, the equation of Puasson, a method of large particles, a condition of stability of Kuranta-Fridrihsa-Levi, a settlement grid, a step on time, a method of Runge-Kutta.
