WRF update history:
======================================
In WRFV3 directory, type 'configure' - this will create a configure.wrf file that has appropriate compile options for the supported computers.
Note: WRF requires netCDF library. If your netCDF library is installed in some odd directory, set environment variable NETCDF before you type 'configure'. For example,
setenv NETCDF /usr/local/netcdf-pgiType 'compile case_name' where you can find the case_names by simply typing compile. The following are available:
compile em_b_wave compile em_grav2d_x compile em_heldsuarez compile em_hill2d_x compile em_les compile em_quarter_ss compile em_real compile em_seabreeze2d_x compile em_convrad compile em_squall2d_x compile em_squall2d_y compile em_scm_xy compile em_tropical_cyclone
Notes: 1. If you are going to create model output file that is more than 2Gb, you should consider using netCDF large file support function. To activate this, one must set the environment variable WRFIO_NCD_LARGE_FILE_SUPPORT. In c-shell environment, do
setenv WRFIO_NCD_LARGE_FILE_SUPPORT 1
This becomes default since V3.9.
Since V3.2, we support using multiple processors for compilation. The default number of processors used is 2. But if you have any problem with compilation, please try using one processor to compile. To do this, set the following environment variable before compile:
setenv J "-j 1"
If sucessful, this will create either real.exe or ideal.exe and wrf.exe in directory main/, and the appropriate executables will be linked into the test directoires under test/case_name, or run/.
cd to the appropriate test or run directory to run ideal/real/wrf.
If it is one of the idealized cases (b_wave, hill2d_x, grav2d_x, quarter_ss, squall2d_x, squall2d_y, em_les or em_heldsuarez), cd the the appropriate directory, type
./ideal.exe
to produce wrfinput_d01 file for wrf model. Then type
./wrf.exe
to run.
If it is real-data case (real), place files from WPS (met_em.*) in the appropriate directory, type
./real.exe
to produce wrfbdy_d01 and wrfinput_d01. Then type
./wrf.exe
to run.
If you use mpich, type
mpirun -np number-of-processors wrf.exe
