Improved convergence to the steady state of the Euler equations by enhanced wave propagation
The convergence to the numerical solution of the stationary Euler equations in two and three dimensions is studied. The basic iterative algorithms are Runge-Kutta time-stepping, GMRES, and a modified GMRES method. Convergence acceleration is achieved by two preconditioning techniques: residue smoothing and multigrid iteration.
