Title:

Multiscale Cell Based Coarsening

Abstract:

Whether tracking the eye of a storm, the leading edge of a wildfire, or the front of a chemical reaction, one finds that significant change occurs at the thin edge of an advancing line. Tracking of such change-fronts comes in myriad forms with a wide variety of applications expressible as PDEs. Expanding on Amu Harten's ideas, we construct an alternative to wavelet-based grid refinement, a multiresolution coarsening method that is capable of capturing sharp gradients across different scales, thus improving PDE-based simulations by concentrating computational resources where the solution varies sharply.
