Spatial modeling of breaking effects in nonlinear plasma oscillations

Previously, the authors numerically and analytically studied the effect of off-axis breaking of relativistic and nonrelativistic cylindrical axisymmetric nonlinear plasma oscillations in the framework of a one-dimensional hydrodynamic model. In this paper, the explicit method of second order accuracy in Eulerian variables is implemented for a two-dimensional simulation of this effect on computers with distributed memory. The numerical results obtained on the “Chebyshev” MSU supercomputer complex using a hybrid parallel code are discussed. These results can be compared with the results obtained in the framework of the one-dimensional model.
