| | 6 | Routage simple is developped by Yann Meurdesoif using the same physics as the standard routage but having another parallelization. |
| | 7 | It is currently available in branch ORCHIDEE_2_2. |
| | 8 | |
| | 9 | == Do as follow if running without libIGCM == |
| | 10 | * Use revision 7526 or more recent on branch ORCHIDEE_2_2. Compile as default. |
| | 11 | * Use file ${R_IN}/SRF/ROUTING/routing_simple.nc instead of standard routing.nc file. The file should keep the name routing_simple.nc in the run directory. R_IN=/projsu/igcmg/IGCM at ciclad and exists as well at jean-zay, irene and obelix. |
| | 12 | * In orchidee.def (or run.def) set: |
| | 13 | {{{ |
| | 14 | RIVER_ROUTING=y |
| | 15 | ROUTING_METHOD = simple |
| | 16 | }}} |
| | 17 | * Use all xml files in ORCHIDEE/src_xml including context_routing_orchidee.xml |
| | 18 | * Add in iodef.xml after inclusion of the context_orchidee.xml: |
| | 19 | {{{ |
| | 20 | <context id="orchidee" src="./context_routing_orchidee.xml"/> |
| | 21 | }}} |
| | 22 | * There is a new restart file specific for the routage simple. It is created at first start of the model. It is called routing_restart.nc when written and to restart the simulation it should be called routing_start.nc. |
| | 23 | * A new output file is written called diag_routing.nc. Some output are also avaialble in sechiba_history.nc. |
| | 24 | |
| | 25 | |
| | 26 | == Do as follow when using libIGCM == |
| | 27 | * With LMDZOR |
| | 28 | * Install LMDZOR_v6.2_work. Update to have above revision 7526 or later for the source code and the latest revision of the config/LMDZOR_v6 folder. |
| | 29 | * Create a new experiment using LMDZOR/clim_pdControl |
| | 30 | * In your experiment folder, copy COMP/orchidee.card_routage_simple into COMP/orchidee.card |
| | 31 | * If you want another experiment, see the difference to add in orchidee.card by comparing EXPERIMENTS/LMDZOR/clim_pdControl/COMP/orchidee.card and EXPERIMENTS/LMDZOR/clim_pdControl/COMP/orchidee.card_routage_simple |
| | 32 | * With ORCHIDEE offline (under edition) |
| | 33 | * Install ORCHIDEE_2_2. You will get the HEAD of ORCHIDEE and ORCHIDEE_OL. Compile as usual. |
| | 34 | * Copy the experiement you want to use and make following modifications: |
| | 35 | * Set in PARAM/run.def: |
| | 36 | {{{ |
| | 37 | RIVER_ROUTING=y |
| | 38 | ROUTING_METHOD = simple |
| | 39 | }}} |
| | 40 | * Modify in COMP/sechiba.card |
| | 41 | * Add xml file in COMP/orchidee_ol.card (or orchideedriver.card if using experiment with the new driver) |
