Parallelization of algorithms to solve the plasma physics problems using the hybrid models
Abstract:
As it is known, the full description of many processes in the plasma physics problems is based on the Vlasov kinetic equation and the Maxwell system of equations. However, the difficulties of the numerical implementation of such models make difficulties for using them when carrying out computations even on modern computational systems. It deals with the large difference in space and time scales for electrons and ions. In order to reduce the cost during the numerical modelling the hybrid models are used. In these models ions are described by the Vlasov kinetic equation when electrons are via the equations of the magnetohydrodynamics (MHD). The solving of the MHD equations requires lesser computational costs, then the development of such models is very important. A hybrid numerical model based on the particle-in-cell (PIC) method for model plasma flow interactions is considered. There have been carried out the algorithm parallelization and computational tests.
