Description	We work with the system of equations describing non-stationary compressible fluid flow (2D,3D), i.e. the Euler equations, the Navier-Stokes (NS) equations, and we focus on the numerical solution of these equations and on the boundary conditions. Many boundary conditions (i.e. fixed, linearized) bring non-physical errors into the solution, slowing down the convergent process, or even ruining the solution in the whole domain. We use the analysis of the Riemann problem for the construction of the boundary conditions in order to match the experimental data. We show, that the unknown one-side initial condition for the local Riemann problem can be partially replaced by the suitable complementary condition. We suggest such complementary conditions (by preference of pressure, velocity, total quantities,...) giving physically relevant data. Algorithms were coded and used within our own developed code for the solution of the Euler, NS, and the RANS equations. Numerical examples show superior behavior of these boundary conditions. Our method for the construction of the boundary conditions is robust and its use accelerates the solver convergence to the desired solution.
