    5 LMDZOR_v4 is the current version using LMDZ and ORCHIDEE. It is a configuration in phase with the coupled model IPSL-CM5. It can be used with LMDZ4 production version LMDZ4_AR5 or with one of the latest versions of LMDZ5/trunk.  
     5LMDZOR_v4 is the current version using LMDZ and ORCHIDEE. It is a configuration in phase with the coupled model IPSLCM5A. It can be used with LMDZ4 production version LMDZ4_AR5 or with one of the latest versions of LMDZ5/trunk.  
    66Before running this model set up, choose between 2 mode : Interannual AMIP simulation or climatologic simulation. No default setup exists. Modifications done by the user in the lmdz.card or orchidee.card are often necessary to adapt to a specific simulation. Modifications in lmdz.driver or orchidee.driver are less often necessary.

The variables should be at monthly time serie format. For exemple for the coupled IPSLCM5A rcp4.5 simulation, at CCRT use files :

    63 This configuration only contains only one directory for running the gcm.e : LMDZOR. This directory can be used for different type of simulation for exemple AMIP interannual or climatolical run. Or nudged run with regular or zoomed grid. Only the .card changes for different run. The PARAM directory and the .driver are the same. Two possibilities are predefined using the different .cards that are available. To do a climatological simulation, use cards with suffix ''_Climat'', do following link :

    82  * Check memory in your job. For higher resolutions you may need to add threads just to have more memory. You must then compile in mpi mode (default for create_etat0_limit.e.para) and not mixt mpi_openmpi. In your job, add '''@ parallel_threads = 8'''. This gives you 8 times more memory per process mpi availible and you can multiply data_limit and stack_limit by 8. When adding threads you should remove '''@ resources = !ConsumableCpus(1)'''. For exemple for resolution 280x280x39 put in your job :

    143143To activate the patch modifications in CREATE/COMP/lmdz.card_Interannuel is needed. Add the files to interpolate in [!BoundaryFiles]/List and in [!OutputFiles]/List and add the paragraf [Nudge_Interp] in the end of lmdz.card. Here below is an exemple how to add u. In the same lmdz.card it is possible to add different files u,v,t,... using the same syntax :
