The ''install_lmdz.sh'' script is a Bash script that aims at being an "installer" for LMDZ of Linux machines.

In practice it runs a succession of mandatory steps to install and run the model from scratch, namely:
* Download and install required libraries (NetCDF, IOIPSL and possibly XIOS)
* Download the source code (LMDZ and ORCHIDEE), compile it and run a test (bench) simulation

It has many options and features; a good starting point (short of reading and digesting the Bash script itself) is to run '''install_lmdz.sh -h''' to learn about these, which should yield something like:
<pre>
install_lmdz.sh
./install_lmdz.sh [ -v version ] [ -r svn_release ]
[ -parallel PARA ] [ -d GRID_RESOLUTION ] [ -bench 0/1 ]
[-name LOCAL_MODEL_NAME] [-gprof] [-opt_makelmdz] [-rad RADIATIF]

-v "version" like 20150828.trunk
see http://www.lmd.jussieu.fr/~lmdz/Distrib/LISMOI.trunk

-r "svn_release" : either the svn release number or "last"

-compiler gfortran|ifort|pgf90 (default: gfortran)

-parallel PARA : can be mpi_omp (mpi with openMP) or none (for sequential)

-d GRID_RESOLUTION should be among the available benchs if -bench 1
among which : 48x36x19, 48x36x39
if wanting to run a bench simulation in addition to compilation
default : 48x36x19

-bench activating the bench or not (0/1). Default 1

-name LOCAL_MODEL_NAME : default = LMDZversion.release

-netcdf PATH : full path to an existing installed NetCDF library
(without -netcdf: also download and install the NetCDF library)

-xios also download and compile the XIOS library
(requires the NetCDF4-HDF5 library, also installed by default)
(requires to also have -parallel mpi_omp)

-gprof to compile with -pg to enable profiling with gprof

-cosp to run without our with cospv1 or cospv2 [none/v1/v2]

-rad RADIATIF can be old, rrtm or ecrad radiatif code

-nofcm to compile without fcm

-SCM install 1D version automatically

-debug compile everything in debug mode

-opt_makelmdz to call makelmdz or makelmdz_fcm with additional options

-physiq to choose which physics package to use

-env_file specify an arch.env file to overwrite the existing one

-veget surface model to run [NONE/CMIP6/xxxx]
</pre>

Note that the ''install_lmdz.sh'' script is not the only way to install LMDZ; one can manually do the various key steps (quite possibly adapted to the specificities of the machine that is used).
