Building a Solver Based on PyClaw for the Solution of the Multi-Layer Shallow Water Equations


The multi-layer shallow water equations are an active topic for researchers in geophysical fluid dynamics looking for ways to increase the validity of shallow water modeling techniques without using a fully three dimensional model which may be too costly for the domain size being looked at. In this talk we will step through the effort needed to convert a Fortran based solver to one using the PyClaw framework, a Python framework targeted at the solution of hyperbolic conservation laws. Once the application is converted the ease of implementing parallel and other solver strategies is greatly simplified. Discussion of how this is accomplished and design decisions and future extensions to PyClaw will also be presented.
