MPEG movie of evolution with ZERO boundaries
Zero boundary convergence test. The graph below shows the convergence factor as a function of time. At t=1.0 and t=2.0 there are variations due to the boundaries.

MPEG movie of evolution with PERIODIC boundaries Periodic boundary convergence test. The graph below shows the convergence factor as a function of time. At t=1.0 and t=2.0 there are variations due to the boundaries.
