This page follows a manual for installing Mars Dynamico


1. Install the LMDZ Mars GCM and newstart 

 a) make sure u have the datafir and all of the *.def files. 
 b) create start.nc and startfi.nc

2. Compile start2archive_SSO 

 a) run : makelmdz_fcm -arch <archive> -d <dimensions (lonxlatxalt)>  -p mars start2archive_SSO to create start_archive
 b) run strart2archice_SSO 
 c) cp start_archive.nc to the dynamico_runs folder

3. Install Dynamico 

 a) use the following link to access the wiki page of Dynamico    https://lmdz-forge.lmd.jussieu.fr/mediawiki/Planets/index.php/The_DYNAMICO_dynamical_core
 b)  git clone https://gitlab.in2p3.fr/ipsl/projets/dynamico/dynamico.git
 c) install XIOS, follow this link to access the wiki page of XIOS
    1. if the make_xios dont work try this : ./make_xios --prod  --arch ifort_MESOIPSL --arch_path ../ARCH --job 8 --full
 d) move back to dynamico folder and run  ./make_icosa -parallel <parralel_component> -with_xios -arch <archive> -job 8
    if it doesnt work again add the arch path to ../ARCH

4. Create an initial condiations files for dynamico by running a dynamico simulation without the physics. 

 a) Compile make_icosa_lmdz in trunk/ICOSA_LMDZ
 b) Copy from icosa_lmdz/bin/icosa_lmdz.exe to a dynamico_runs folder
 c) Copy the xml files and the start files and the def files in the dynamico_runs directory and have access to the datadir.
    variable "nivsigs" needs be renamed "sigs" (XIOS requires CF-compliant files) (RV: No neeeded anymore)
    ncrename -vnivsigs,sigs start_archive.nc
    input file start_archive.nc need be converted to NetCDF4 format
    nccopy -k 4 start_archive.nc start_archive_nc4.nc

5. run dynamic. 

 a) In run_icosa.def change to run_length=1500, etat_isothermal_temp=200, etat=isothermal and startphy_file=false(not start_file)
 b) copy datadir to the running directory
 c) run icosa_lmdz.exe 
 d) copy the files outputed by icosa_lmdz.exe
     1. cp restartfi.nc startphy_icosa_ref.nc
     2. cp restart_icosa.nc start_icosa_ref.nc

6. move to LMDZ.mars/util/startarchive2icosa then change compile script to adapt for the right location of XIOS and run compile u should get start_archive2icosa and rearrange_startphy 

 a) copy start_archive2icosa and rearrange_startphy to the dynamico_runs folder.
 b) Create surface_nc4.nc and copy it dynamico_runs folder
 c) source arch.env
 d) run  ./start_archive2icosa as a job (requires a lot of memory) and make sure that Iodef.xml is the one for compile.
 e) the script create start_icosa_prefinalize.nc and  startfi_prefinalize.nc
 f) copy icosa_finalize script form /trunk/LMDZ.MARS/util/startarchive2icosa/icosa_finalize.bash to dynamico_runs folder
 g) change the XIOS and the for startfi0.nc  paths in icosa_finalize.bash and run it. It adds and changes variables in the startfiles.
 h) The scripts outputs startfi.nc and start_icosa.nc

7. update the tracer name in startfi for each tracer for example: ncrename -v ccn_number_surf,ccn_number startfi.nc

8. Run Dynamico simulation 

 a) change the iodef.xml
 b) change in run_icosa.def etat0=start_file and add etat0_start_file_colocated=true
