RESUMO

Given in this article is a new method of boundary conditions statement at the remote boundary for use in numerical methods of finite volume. Simple relations that simulate the remote boundary are universal and do not depend on the shape of the boundary and its vicinity to the body (up to distances comparable to body size). Moreover, they use data only from the boundary area without considering the streamlined body. Application of this algorithm is considered by the example of two-dimensional problems. Shown here is the advantage of a new method over Riemann standard conditions for accuracy of calculations on computational grids near the boundary.
