The global coupled model is not restart reproducible when waves are included. It also cannot be run in debug mode. Both are operational requirements.
Solution
Implement a new mesh-based NUOPC cap for the S2SW and HAFSW applications which is restart reproducible and which can be run in debug mode. The new mesh-based cap allows the WW3 component the ability to run as shel or multigrid via configuration namelist. Currently only a single grid is supported when run as multigrid. Both options are restart reproducible and are B4B when cross-verified (shel vs a multi baseline and vice versa). The WW3 can optionally produce NetCDF files containing the gridded fields using configuration settings in nems.configure.
In order to run the mesh cap in UWM, the following files are required:
A mesh file describing the model grid.
For HAFSW, the mesh.hafs.nc file can be produced using NCO (netCDF operators) and the ESMF command line tool ESMF_Scrip2Unstruct. Note the mesh for any rectilinear grid can be created in a similar manner.
For S2SW, the creategridfiles.sh utility can be used to create the required files (mod_def.mx100,mod_def.mx050, mod_def.mx025) using the lat,lon,mask and depth arrays generated from the cpld_gridgen utility.
Integrate WW3 CMake build #1074. The new Cmake build being added to UWM for the WW3 will need to accommodate a second WW3 build; one for use with the connectors and the ATMW app and a second build utilizing the new mesh cap for the S2SW and HAFSW apps.
