Compilation instructions

1.- Extraction of the source code:

$ svn co ​http://svn.lmd.jussieu.fr/LMDZ_WRF LMDZ_WRF

1.- Copy (not int the repository folder...) folder 'WRFV3' to the desired spatial resolution (F77 legacy). As example one for 80x90x39

$ cp -R WRFV3 ${WORKDIR}/WRFV3_80x90x39

1.- Go to the ${WORKDIR} and compile there

$ cd ${WORKDIR}/WRFV3_80x90x39

1.- Define domain size for LMDZ editing file lmdz/dimensions.h (see documentation for more details)

$ cat lmdz/dimensions.h

INTEGER iim,jjm,llm,ndm,wiim,wjjm,wbdym

PARAMETER (iim= 1, jjm=7031, llm=38,ndm=1,wiim=79,wjjm=89,wbdym=5)

jjm = (dimx-1) * (dimy -1) llm = (dimz - 1) wiim = dimx - 1 wjjm = dimy - 1 wbdym = 5 (up to now, mandatory to run WRF with 5 grid points in the sponge zone)

1. run script 'tools/prepare_compilation.bash' ('-h', for help. copy netCDF libraries and other staff not automatized) $ ./prepare_compilation.bash [WRF_LMDZsrc] [NETCDFhome] ${WORKDIR}/WRFV3_80x90x39

1. prepare compilation (ready for 'lmd' machines in serial) if not, edit
   1. $ ./configure
   2. add pre-compiler flag' -DLMDZ after -DNETCDF (inside configure.wrf)
   3. modify 'lmdz/Makefile with that values from the 'configure.wrf'
2. prepare compilation modifying Registry files (already done, have a look just in case):
   1. $ ls -lrta Registry/Registry?.EM Registry/Registry?.EM -> Registry.EM.LMDZ
   2. $ ls -lrta Registry/registry.dimspec -> registry.dimspec.lmdz

1. Compile as usual $ compile em_real >& compile.log

1. Compile manually a lmdz subroutine (not working, not knowing why). Example with gfortran serial in lmdz machines $ cd lmdz $ gfortran -O3 -ftree-vectorize -ftree-loop-linear -funroll-loops -w -ffree-form -ffree-line-length-none -fconvert=big-endian -frecord-marker=4 -fconvert=big-endian -frecord-marker=4 -O3 -ftree-vectorize -ftree-loop-linear -funroll-loops -w -ffree-form -ffree-line-length-none -fconvert=big-endian -frecord-marker=4 -g -O0 -fbacktrace -Wall -fbounds-check -c -L/u/lflmd/bin/gcc_netcdf-4.3.0/lib -lnetcdf -lnetcdff -I/u/lflmd/bin/gcc_netcdf-4.3.0/include lmdz_wrf_variables_mod.f90 $ cd ..

1. run script for second time 'tools/prepare_compilation.bash' $ ./prepare_compilation.bash [WRF_LMDZsrc] [NETCDFhome] ${WORKDIR}/WRFV3_80x90x39

1. Recompile as usual $ compile em_real >& compile.log

1. Checking compilation (empty outputs) $ cat -n compile.log | grep Error $ cat -n compile.log | grep Erreur (just in case you are in a French speaking computer)

1. Running simulation
   1. Run all the steps 'WPS' and 'real.exe' as usual
   2. folder 'WRFV3/run' is not completed (no binaries in repository!), thus get a copy of the right WRF version and use the original source
   3. Edit and modify 'namelist.input' and all the LMDZ *def files provided in 'run' folder: 'config.def', 'gcm.def', 'physiq.def', 'run.def', 'traceur.def'

1. You're done, Have fun!
