ON THE PROBLEM OF BOUNDARY CONDITIONS IN THE MULTIDIMENSIONAL NODAL METHOD OF CHARACTERISTICS

The setting of boundary conditions on curvilinear walls in application to the multidimensional nodal method of characteristics is discussed, which is based on splitting the initial system of equations into a number of one-dimensional subsystems along the coordinate directions. For the boundary points located on curvilinear impermeable surfaces, a calculation method based on the procedure of fi ctitious nodes is suggested, with the use of which a number of test problems with self-similar solutions have been calculated.
