The paper is devoted to the description of some difference algorithms for numerical simulation of environment problems. The model includes Havier-Stokes equations for background wind components. The impurity transfer is modeled with diffusion and convection equation. Discrete approximation generation and numerical method selection are discussed. Some computational results are given.

The paper presents the implementation practices for axisymmetric gas-dynamic flows in heterogeneous medium; the calculations run on STMD PS-2100 computer. The LEGAK method was previously implemented on BESM-6 and ES-1G66. When porting the method to a SIMD multiprocessor only those modifications were made that are needed for a more efficient algorithm parallelization. The main algorithms are given and the organizational code structure is presented for SIMD architectures.
