…l mesh by projecting a rectangular mesh composed of perfect hexagons to the sphere using a Lambert conformal projection. The hex_projection directory in the MPAS-Tools/mesh_tools directory is new and the utility is placed in hex_projection directory. The README file provides directions for building and running the utility, and a default case is specified in the namelist.projections file used as input to the utility. The utility creates an MPAS grid file (netcdf) and a graph partition file (ascii) for the mesh. The grid file includes the masks needed for regional simulations in MPAS-Atmosphere, along with a mesh_density function. The current mask configuration has 5 levels in the relaxation zone and 2 levels in the specified zone. This is hardwired in the utility, consistent with the hardwired configuration in MPAS-Atmosphere.
