Foil 23 Stability Conditions for Beam Warming Equations

From Introduction to Physics and Numerics of NAS Benchmarks CPSP713 Case studies in Computational Science -- Spring Semester 1996. by Geoffrey C. Fox
1 Note that Explicit Euler was always unstable for convection equation but for our case, the artificial viscosity ensures that explicit Euler is stable for small enough time step D t
2 Implicit Euler is always stable for dissipative systems because these by definition have Re(W) negative.
