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 fictitious nodes is suggested, with the use of which a number of test problems with self-similar solutions have been calculated.
