Problems of mathematical modeling of blood flow in large vessels are considered. A second order spatial and time discretization SSP-TVD-scheme is implemented for the hemodynamics problem. A number of test problems with analytical solutions are proposed. In particular, a solution for Riemann problem is given. Various features of boundary conditions implementation for the system of hemodynamics equations are discussed. Questions of convergence and a choice of grid parameters for various schemes are investigated.
