In order to solve the Vlasov-Liouville equation PIC method is applied. For solving the Poisson equation a combination of iterative processes is applied. The physical phenomenon under study is the galactic spiral structure. It is the specific pattern observed in many galaxies including the Milky Way. The subject is of great interest, because there is still no complete theory.
Numerical simulations are the main means of research because direct experiments are impossible.
