In the new physgrid topography toolchain, we need to run this utility twice. On ne30pg2 (for example), it would previously issue a message and abort. However, with the stop statement removed, the resulting topo dataset appears fine. So comment it out. Abort immediately if --smooth-topography is an invalid file. Reduce the number of progress messages.
There are two new topography tools to support physgrid.
The first is a simple converter. The input is an old GLL topography file. The
output is a topography file in the new GLL-physgrid format. SGH, SGH30,
LANDFRAC, and LANDM_COSLAT are not quite as good as with second tool, but this
converter works in one step:
$ cat input.nl
&ctl_nl
ne = 30
/
&vert_nl
/
&analysis_nl
tool = 'topo_convert'
infilenames = 'USGS-gtopo30_ne30np4_16xdel2-PFC-consistentSGH.nc', 'USGS-gtopo30_ne30np4pg2_16xdel2-PFC-consistentSGH_converted'
/
mpirun -np 8 homme_tool < input.nl
The second tool provides the best-quality GLL-physgrid file. It has five steps:
1. TempestRemap:
${tempest_root}/bin/GenerateCSMesh --alt --res 30 --file topo2/ne30.g
${tempest_root}/bin/GenerateVolumetricMesh --in topo2/ne30.g --out topo2/ne30pg2.g --np 2 --uniform
${tempest_root}/bin/GenerateVolumetricMesh --in topo2/ne30.g --out topo2/ne30pg4.g --np 4 --uniform
${tempest_root}/bin/ConvertExodusToSCRIP --in topo2/ne30pg4.g --out topo2/ne30pg4_scrip.nc
2. cube_to_target, run 1:
${e3sm_root}/components/cam/tools/topo_tool/cube_to_target \
--target-grid topo2/ne30pg4_scrip.nc \
--input-topography topo2/USGS-topo-cube3000.nc \
--output-topography topo2/ne30pg4_c2t_topo.nc
3. homme_tool:
$ cat input.nl
&ctl_nl
ne = 30
smooth_phis_numcycle = 16
smooth_phis_nudt = 28e7
hypervis_scaling = 0
hypervis_order = 2
se_ftype = 2 ! actually output NPHYS; overloaded use of ftype
/
&vert_nl
/
&analysis_nl
tool = 'topo_pgn_to_smoothed'
infilenames = 'ne30pg4_c2t_topo.nc', 'ne30np4pg2_smoothed_phis'
/
mpirun -np 8 ./homme_tool < input.nl
4. cube_to_target, run 2:
${e3sm_root}/components/cam/tools/topo_tool/cube_to_target \
--target-grid ne30pg2_scrip.nc \
--input-topography USGS-topo-cube3000.nc \
--smoothed-topography ne30np4pg2_smoothed_phis1.nc \
--output-topography USGS-gtopo30_ne30np4pg2_16xdel2.nc
5. ncks
ncks -A ne30np4pg2_smoothed_phis1.nc USGS-gtopo30_ne30np4pg2_16xdel2.nc
USGS-gtopo30_ne30np4pg2_16xdel2.nc is the final GLL-physgrid topography file.
In particular, clean up Kokkos. This is called from prim_finalize.

Call prim_finalize from EAM, and call Kokkos::finalize when using SL transport (indirectly) from prim_finalize. Final tool for physgrid topography file. Fix reading of GLL PHIS_d when reading the new physgrid topo file format. [BFB]
