Finite-difference approximations of elastic forces on the staggered moving grid were constructed. For the displacement vectors at the irregular grids in which topological and geometrical structures are subjected to minimal reasonable restrictions, wi

The paper deals with some typical problems of gas hydrates dissociation in a porous medium, which in the first approximation can be reduced to one-dimensional. The research aims to study the mutual effects of underground gas hydrates and climate chan

A family of two-layer completely conservative difference schemes is constructed for the spatially one-dimensional equations of gas dynamics. It is possible to obtain complete conservativeness of the difference scheme by profiling the time weights in

THE EQUATIONS of a one-dimensional unsteady gas-dynamic flow with sources of mass, momentum and energy are considered. The role of the sources is explained by the example of the self-similar problem of a piston with the aid of theoretical analysis, a

The convergence of difference schemes for Poisson's equation, based on arbitrary irregular grids constructed by the method of reference functions, is investigated with regard to solutions of class W2,2. It is shown that for quite weak restrictions on
