Error in lmdz.driver in v6 for CARBON_CYCLE

[jgipsl]

In ​lmdz.driver in ATM_Carbon_Update, rev 2410, the follwing section can not work since the change by using IGCM_comp_modifyDefFile :

    if [ ${lmdz_UserChoices_CARBON_CYCLE} = historical ] ; then
            # Modify co2_ppm in config.def only for historical run
            # If not historical run, keep co2_ppm value set earlier by IGCM_comp_modifyDefFile
        IGCM_comp_modifyDefFile nonblocker config.def co2_ppm     ${CO2_ppm}
    fi

The function IGCM_comp_modifyDefFile can only change the value of a parameter if it is equal AUTO.

[jgipsl]

The option force can be used with IGCM_comp_modifyDefFile to overwrite a value even if it is not set =AUTO.
