Set up a simulation


First of all see official documentation

http://forge.ipsl.jussieu.fr/libigcm/wiki/

How to manage restart files ( in the same simulation )

In modipsl/config/ORCA2_LIM/IGCM00/config.card
file you have to set duration of your experience and setting PeriodLength parameter, so you create restart files.

( for example : if you have and experience of 10 years and a PeriodLength of 1 year, you will have 10 restart files )

#— Début et fin de Job
#— "YYYY-MM-DD"
Date Begin?=2001-01-01
Date End?=2010-12-31
#============================
#— 1Y, 1M, 5D, 1D
Period Length?=1Y

Note : If you want to use restart data from another simulation ( already run not in this moment ) you have to manage "Restarts" part of config.card

#================
#D— Restarts -
[Restarts]

How to have mail of end of Job, on ccrt's machines

on mercure: in Job_Name: #PBS -M name@mail
on platine: In Job_Name: #BSUB -u name@mail

How to manage write output frequency

in modipsl/config/ORCA2_LIM/IGCM00/config.card you have to set WriteFrequency of your experience

( for example : if you want output files every 1 month you have to put for Ocean

#===================
#D— OCE -
[OCE]
Write Frequency?="1M"

and if you want output files every 1 month you have to put for ICE

#===================
#D— ICE -
[ICE]
Write Frequency?="1M"

)

How to manage calendar type

in modipsl/config/ORCA2_LIM/IGCM00/config.card you have to set CalendarType like 360d or leap or noleap

# for 360d :

you have to be careful at

Date End?=2010-12-30

because every month has 30 days

If you put for example Date End?=2005-12-31, you will have another run, of duration like your PeriodLength

# for noleap :

you have to be careful at

WriteFrequency="1M"

and PeriodLength=1M

because in this moment simulation of 365 days it is possible only with a write output frequency of one month, and restart every month.

( If you put a different value for WriteFrequency you will not find restart files )

How to manage rdt ( i.e. timestep )

in modipsl/config/ORCA2_LIM/IGCM00/COMP/nemo.driver you have to change parameter : ORCA_NPDT_JOUR=15

( 15 corresponds to 86400s/5760s; it does mean that in one day you have 15 iterations; and it does mean that timestep is 5760)

How to manage Interannual or Climatological Runs

in modipsl/config/ORCA2_LIM/IGCM00/COMP/opa9.card )

You have to set

# Interannual_Run y if you want to do interannual runs or n if you want to do climatological runs

# In [Interannual] section you have to fill List_jobsbc of file names like they appear in namelist.
( for example if you want to do interannual run using clio bulk core you can put :

List_jobsbc=(flx, taux_1m, tauy_1m)

)

How to manage Interannual or Climatological Runs

in modipsl/config/ORCA2_LIM/IGCM00/PARAM/namelist

You have to set in "namsbc" part if you want to do climatological run and if you want to do an interpolation :
time interpol. (logical) and clim (T/F)
