Software implementation of algoritms for numerical solution of 2D gas dynamics operator-difference grid problems by using the C++ class system

Programming tools for the software implementation of operator algorithms for numerical solution of operator-difference equations for gas dynamics grid problems are developed on the basis of the object-oriented programming technique. The operator approach gives the ability to express grid problems in a uniform way through systems of operator equations for various dimensions, coordinate systems, types of boundary conditions and approximations, and the algorithms in use. The object-oriented programming technique allows one to realize the direct ability to work with grid functions as elements of finite-dimensional spaces as well as with operators acting in these spaces and with operator equations and operator algorithms for solving these equations.
