With the development of computer engineering power and appearance of computation systems with large-scale parallelism a real chance to calculate gas dynamic three-dimensional problems opens during the last years. Today most of techniques developed in the mathematical department of RFNC-VNIIEF come to a new level of development — 3-D modeling of mathematical physics procedures. One of these techniques is MEDUZA. The principal characteristics of the technique are the use of irregular grid, centering of all the gas-dynamic quantities in the node, availability of a variable differential pattern for numerical integration of differential equations and possibility to change grid topology at the solution time. Contact borders are described using mixed cells calculated with concentration method.
