Maximally-fast coarsening algorithms
We present maximally-fast numerical algorithms for conserved coarsening
systems that are stable and accurate with a growing natural time-step . For non-conserved systems, only effectively finite timesteps
are accessible for similar unconditionally stable algorithms. We compare the
scaling structure obtained from our maximally-fast conserved systems directly
against the standard fixed-timestep Euler algorithm, and find that the error
scales as -- so arbitrary accuracy can be achieved.Comment: 5 pages, 3 postscript figures, Late
