Toward a Non-Hydrostatic HOMME
- Univ. of Colorado, Boulder, CO (United States); Office of Science
CSLAM integration into HOMME: The finite-volume based CSLAM algorithm is designed for a uniform-resolution equiangular central projection on the cubed-sphere for the control volumes (cells). However, the HOMME model uses spectral elements that contain highly irregular cells within. Thus, to implement CSLAM in the HOMME framework presents two major challenges: (1) extend CSLAM to general quadrilateral meshes and (2) widen the halo regions in HOMME to incorporate monotonicity constraints. Since the HOMME communication package gathers only the points on the surface of its nearest-neighbor elements, widening the halo region is a significant data structure change in HOMME that required substantial software engineering support
