      Brief description of parallel computation arrangement for solving 3D heat conduction equation using orthogonal computational blосk-matrix grids is riven. Combination of the parallel region-by-region computation scheme with sweep parallelization is used. The efficiency of parallelization algorithms is numerically studied. Computations have been performed using 8 processor computer system MP-3.

      Numerical algorithm is developed describing in 2D geometry layer-by- layer burning front propagation at a velocity depending on local gas dynamic material parameters in each front point. The algorithm is based on the well known physical Huygens principle for wave front propagation. Test results are given, good agreement between the results obtained and exact solutions is demonstrated.
