Abstract
In this paper we present a program for simulation of the two-component protoplanetary disc evolution. The model includes gas dynamics and collisionless solid body dynamics. Multigrid method for solution of Poisson equation in cylindrical coordinate system is described. An essentially parallel Poisson equation solver is constructed by means of applying Fast Fourier Transform along the angular direction. Processor workload rearrangement is performed in order to increase the speedup. The results of computational experiments are given to demonstrate the physical validity of the program.
