A method for relaxing the Courant-Friedrich-Levy condition in time-explicit schemes [PDF]
Astronomy & Astrophysics, 2005 We present a method for relaxing the Courant-Friedrich-Levy (CFL) condition, which limits the time step size in explicit numerical methods in computational fluid dynamics. The method is based on re-formulating explicit methods in matrix form. Here an explicit method appears as a special case in which the global matrix of coefficients is replaced by the

The use of classical Lax–Friedrichs Riemann solvers with discontinuous Galerkin methods [PDF]
International Journal for Numerical Methods in Fluids, 2002 AbstractWhile conducting a von Neumann stability analysis of discontinuous Galerkin methods we discovered that the classic Lax–Friedrichs Riemann solver is unstable for all time‐step sizes. We describe a simple modification of the Riemann solver's dissipation returns the method to stability.
