This tutorial is designed
  * to be used during LMDZ training.
  * to help install multi configuration simulations.

In the current directory, you may
 0/ install the model, if it's not already done
 1/ compile the model
 2/ create initial and boundary conditions on a zoomed (or regular)
      grid
 3/ run the model

Contains :
==========

init.sh : main script that
 1/ creates initial state and boundary conditions -> INITIAL
    if running with Orchidee land model : prepares a preliminary 
       simulation to produce the correponding initial state -> SIMU0
 2/ prepares a first simulation -> SIMU1
 3/ prepares a possible long simulation (month by month) in PROD0
     tu be executed as
      cd PROD0
      ./enchaine.sh
     A new simulation can be started afterward from any month from
     PROD0 with
      cd ../
      ./branche -i PROD0 -o NEWSIM 200003
    
DEF : contains default files .def for setup parameters

get_era.sh : to interpolate ERA reanalysis on the model grid
reb.sh : to "rebuild" outputfile for parallel computation with IOPSL
run_local.sh : to run the model (important for parallel computers)
run_X64_ADA.sh (obsolete) : the same for ada supercomputer at idris (ada was replaced by jean-zay)

NB: If you change the horizontal resolution of LMDZ, you should
    modify some parameters in DEF/gcm.def : 
      --> day_step and iphysiq, in order to satisfy the CFL criteria
      --> dissipation parameters : tetagdiv, tetagrot, tetatemp

Modifications :
===============
2022 : Introducing the possibility to also install the model (FH) 
  The script init.sh checks if the model is installed, and if not, it launches install_lmdz.sh.
2018/12/03 : changing physiq.def from PHYS/physiq.def_NPv6.0.12split
to PHYS/physiq.def_NPv6.1 (FH)
