摘要
The article contains a solution to the problem of wave propagation from two sources in the form of pulsating spheres located in a closed region asymmetrically about its boundary. The solution is produced by the explicit Euler method and the predictor-corrector method. Various types of boundary conditions are considered, including taking into account the "sticking" of the transfer medium to the walls of the closed region and in the form of an absolutely rigid wall, when only the normal velocity component is zero. Isopole potentials are given, as well as velocities and pressures at different points in time. The text of the article contains an analysis of the effect of the steps in time and coordinates on the results of the calculation.
