Warning in WRF moving nest setup

[met-sree]

Dear All,

I recently installed the WRF model with a moving nest configuration by enabling `export TERRAIN_AND_LANDUSE=1` and following the steps outlined in the forum thread: [https://forum.mmm.ucar.edu/threads/...eads/related-to-moving-nesting-warning.8731/).

Since the `types.h` files were not present in our HPC environment, I installed them in a specific location and added the relevant paths during the installation. The steps I took include:

1. Modifying the `makefile` by adding the following line:
```
@cd tools ; /bin/rm -f rpc_test.exe ; $(SCC) -I/scratch/....../Others/libtirpc-1.3.7/include/tirpc -DUSE_TIRPC -o rpc_test.exe rpc_test.c ; $(SCC) -I/scratch/......./Others/libtirpc-1.3.7/include/tirpc -o rpc_test.exe rpc_test.c;
```

2. Updating the `configure.wrf` file to include the necessary library paths:
```
LIB_EXTERNAL = \
-L$(WRF_SRC_ROOT_DIR)/external/io_netcdf -lwrfio_nf -L/scratch/00-TRINITYX_SHARED/APPLICATIONS/packages/netCDF-Fortran/4.6.1-gompi-2024a/lib -lnetcdff -lnetcdf -L/scratch/....../Others/libtirpc-1.3.7/lib -ltirpc
```

The installation completed successfully. However, while running the model, I encountered the following warning:
"Warning: input_from_file turned on for domain 2, input_from_hires disabled."

For your reference, I have attached the `configure.wrf`, `makefile`, `rsl.error.000`, and `namelist` files. You can find them via this link: [ Error - Google Drive ].

I would greatly appreciate any insights or suggestions you may have to address this warning and ensure the model runs as intended.

Thank you in advance for your valuable time and assistance.

Best regards,

I observed in the file /WRF/share/interp_fcn.f90 the following code segment:

IF ( input_from_file .AND. input_from_hires ) THEN
Write(message, '(a,i3,a)') &
"Warning : input_from_file turned on for domain ", nid, ", input_from_hires disabled"
CALL wrf_message(message)
END IF

Is this a check to ensure input_from_file and input_from_hires are never both enabled simultaneously?

Yes, I believe that's correct. If you want to use input_from_hires, then set input_from_file = true for each domain.

Thank you.
