Résumé

The question of the boundary conditions implementation in the previously proposed bicompact schemes is investigated for the linear transfer equation. These schemes are constructed by the method of lines, they are conservative, monotonic and economical, and can be solved by running method. To ensure a high accuracy of the bicompact schemes, the various ways of implementing boundary conditions are proposed. These schemes are based on the $A$-and $L$-stable diagonally implicit Runge–Kutta of third-order approximation for the integration of the transfer equation in time.

Détail

Keywords: linear transport equation, bicompact difference schemes, diagonally implicit Runge–Kutta schemes.
