A Direction Splitting Scheme for Flow Problems in Spherical Shell Geometries

Abstract
In this talk, I will discuss direction-splitting schemes for solving the incompressible and weakly compressible flow problems in a spherical shell region. The equations are solved on overset Yin-Yang grids, combined with spherical coordinate transforms. This approach allows to avoid the singularities at the poles and keeps the grid size relatively uniform. The scheme is implemented in parallel using a domain decomposition iteration, and a direction splitting approach for the local solves.
