The paper describes the parallelization method using 2D grid decomposition, when the lines along each column, calculated on a processor, are overlaid into one and the same column and the whole range. This approach ensures the information completeness on both geometric and thermodynamic parameters of the cells independently of the grid non-orthagonality degree. The paper shows the results of the parallelization accuracy and efficiency test calculations, obtained at different variants of grid decomposition.Keywords: KORONA technique, 2D equation of thermal conductivity, 2D grid decomposition, NEWT parallel solver.
