Evaluation of Mesh Quality, Run-time Efficiency, and Predictability for CPAS Customized Variable-Resolution Mesh

The Customizable Unstructured Mesh Generation (CUMG) enables local mesh refinement in arbitrary shape using user-defined horizontal resolution in any desired locations. Using Hierarchical Time-Stepping (HTS), the model run time is reduced tremendously for meshes with large resolution variation. This study compares the mesh quality, real simulation efficiency, as well as predictive performance of the CPAS customized 128-to-1 km mesh to the MPAS-A standard 60-to-3 km mesh.
