VANT. Ser.: Mat. Mod. Fiz. Proc 2001. Вып.3. С. 3-13.
The paper presents the method for defining mixed cells in D complex and studies two models for computing gas-dynamic and elastic-plastic values in mixed cells. The algorithms for selecting substance separation boundaries in mixed cells and results of problems test computations using mixed cells in D complex are given.

THE DEVELOPMENT OF A METHOD AND PROGRAM FOR GLOBAL AUTOMATIC CORRECTION OF 2-D GRID WITHIN MATHEMATICAL AREAS IN "D" COMPLEX
V.I. Budnikov, V.I. Delov, O.K. Loginova
VANT. Ser.: Mat. Mod. Fiz. Proc 2001. Вып.3. С. 49-59.
The paper describes a technique for automatic determination of the situation, when a global correction of 2-D Lagrangian grid is required. Criteria and algorithms are given to select optimal neighborhood of bad grid nodes, where the grid is
