IPSL-CM5A2 Model

15 minute read

[DISCLAIMER - This ( ~~collaborative effort~~ ) documentation is under development so there might be small errors/wrong statements within the text. Please contact us via mail or github if you think something is not detailed enough or if one step does not work ]

Reference paper for the IPSL-CM5A2 model is Sepulchre et al. 2020. You will find additional information about each component of the model and appropiate references within this paper as well.

Download & Compile the code

Additional documentation on how to download and compile the code can be found here.

Information provided in the following text is well suited for running simulations on IRENE supercomputer (TGCC). Adaptation might be required to run the code on Jean Zay supercomputer (IDRIS) : here.

First you have to choose the version of the model you want to install :

Standard version (ORCA grid - e.g. Modern simulations)
Paleo version (PALEORCA)

Both can be run without ice, which requires additional changes in the code before compilation

/!\ Note that in case you want to compile the code on Jean-Zay supercomputer, you cannot compile the code login on your ‘normal account’ :

_Note that there is a specific front-end to perform compilations tasks. 
This front-end allows you to compile faster and in one go : 
default XIOS compilation may crash because of restricted interactive ressources per user on the standard front-end. 
You can access the compilation front-end by using ssh protocol :
ssh your_login@jean-zay-pp.idris.fr_

In case compilation failed you can use gmake clean to clean the directory

Standard version

In case you want to run simulations with a present-day land sea mask

In the $CCCWORKDIR directory, create a new IPSLCM5A2 directory
In IPSLCM5A2 directory, do a svn to load the required files from the server
Move to modipsl/util directory
Load the model files [ ./model IPSLCM5A2.1 ]
Login & password are required in order to install ORCHIDEE & LMdz => They are available upon request to …

# Load the model

 cd $CCCWORKDIR

 mkdir IPSLCM5A2

 cd IPSLCM5A

 svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk modipsl

 cd modipsl/util

 ./model IPSLCM5A2.1

In case you want to remove ice in Antarctica, additional modification should be done before compiling the code. They are listed paleo section here.

In modipsl/config/IPSLCM5A2 directory, uncomment line 100 from the Makefile
Compile with gmake

  cd ../config/IPSLCM5A2/

  vi Makefile

# Uncomment line 100

# Compile

 gmake

Paleo version

In case you want to run simulations with a paleo land sea mask

In $CCCWORKDIR create new directory that will contain the model (e.g. PALEO-IPSL)

In PALEO-IPSLCM5A2 directory, do a svn to load the required files from the server
In modipsl/util directory do ./model IPSLCM5A2.1 to load the code

# Load the model

 cd $CCCWORKDIR

 mkdir PALEO-IPSL

 cd PALEO-IPSL

 svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk modipsl

 cd modipsl/util

 ./model IPSLCM5A2.1

Additional modification have to be done to switch the code to paleo-version :

In /modipsl/modeles/NEMOGCM/NEMO/OPA_SRC, modify the files in TRA, LDF et DIA directory (copy files from PATH/MODIFICATION-CODE)
In /modipsl/modeles/NEMOGCM/NEMO/TOP_SRC/PISCES, modify the files in P4Z (copy files from PATH/MODIFICATION-CODE/P4Z/)

Without Antarctic ice-sheet

In case you want to remove ice in Antarctica, additional modification should be done before compiling the code : (If you want to run simulation WITH an ice-sheet on Antarctica, just skip this part and directly compile the code)

Before compiling the code, you will have to modify the model component to remove ice:

In modipsl/modeles, create a new directory PALEO_LMDZ that contain two sub-directory PALEO_SRC and ORIGINAL_SRC
In ORIGINAL_SRC copy the 3 original files :
- Modeles/LMDZ/libf/phylmd/hydrol.F90
- Modeles/LMDZ/libf/phylmd/surf_landice_mod.F90
- Modeles/LMDZ/libf/phylmd/fonte_neige_mod.F90
In PALEO_SRC, copy updated (from PATH/MODIFICATION-CODE/phylmd/)
- Paleorca_hydrol.F90_paleorca
- Paleorca _surf_landice_mod.F90_paleorca
- Paleorca_ fonte_neige_mod.F90_paleorca
In /modipsl/modeles/LMDZ/libf/phylmd, copy the 3 files you just added in PALEO_SRC instead of existing hydrol.F90 etc… files (be careful to keep original filel name).

Once all the modification have been done for the version of the model you need :

In modipsl/config/IPSLCM5A2 uncomment line 100 of Makefile
Compile the code (gmake).

  cd ../config/IPSLCM5A2/

  vi Makefile

# Uncomment line 100

# Compile

  gmake

Launch a new simulation

Model architecture

Here are (very!) useful things to know on how the model is organized on the supercomputer

Workspaces

Different model elements and output from simulation can be found in $CCCWORKDIR, $CCCSTOREDIR, $CCSSCRATCHDIR:

On $CCCWORKDIR you find the directory where you install & compile the model (contains code, boundary condition & parameterization files, executables)
$CCCSCRATCHDIR is for temporary storage (it can be erased from time to time). Model output are stored there before being transferred to Storedir by post-processing
$CCCSTOREDIR is the working space where model outputs are permanently stored

Model architecture

“MODELE/modipsl “ directory (exemple : IPSL-CM5A2/modipsl ou PALEOIPSL/modipsl) is subdivided in 4 directory :

« Config » contains parameterization files, experiments directory …
« Modeles » contains code for each different model components
« bin » contains executables. If compilation has been successfull, it should contains 4 individual files
« libIGCM » contains model environment (processor-related stuffs, error outputs etc…)

« MODELE/modipsl/config/IPSLCM5A2 » directory contains several experiments directories :

« GENERAL »
- POST : Post-processing files (Temporal evolution …
- PARAM : Initial parameters & part of boundary conditions (CO2, model timesteps, Orbital parameters etc…)
- DRIVER : Drivers for different model component. Deal with the year per year incrementation for example.
« EXPERIMENTS « : Classic setup for different types of simulations
- LMDZ : Atmosphere-only model
- LMDZOR : Atmosphere + land surface model
- IPSLCM : Coupled model (piControl=preindustrial ou pdControl=present-day)

Run a simulation

Here you will find general indications on which file you have to modify to setup a new simulation

First you need to create a new directory for you simulation. For that you need to choose which model you want to use (Coupled, Atmosphere-Land surface) and to obtain a config.card file, that you can find in the MODELE/modipsl/config/IPSLCM5A2/EXPERIMENT directory.

All the boundary conditions files you will need can be generated with the NetCDF_file_editor.

The following example is to run a coupled simulation from scratch

ELC

1. Generation of simulation directory

Copy the LMDZ config.card in the $CCCWORKDIR/MODELE/modipsl/config/IPSLCM5A2 directory
Modify the config.card :
- JobName= Name_Experiment [example : ELC-SimulationNAme)]
- DateBegin=1854-01-01
- DateEnd=1854-12-30
Create the directory [../../libIGCM/ins_job]

 
 cp EXPERIMENTS/LMDZ/CREATE_clim/config.card .
 
 ../../libIGCM/ins_job

2. Simulation setup

Then you will have to modify the following variables in the boundary condition file COMP/lmdz.card

LMDZ_Physics=AP (l.8)
Modify the config.def_actuel by config.def_preind (l.46)

In the case of paleo simulation you migh need to modify the following lines as well :

(be sure you only change the 1st part of each line and keep the name of the 2nd file in the line as it is in the original lmdz.card )

# Example:

 (PATH/mynew_TopoHR.nc,   Relief.nc),\

Modify the relief file (Relief.nc), with a high resolution topography file (with masked bathymetry) (l.27)
Modify the land-ice file (landiceref.nc), with the land-ice extension file (l.29)
Modify the SST file (amipbc_sst_1x1.nc) with a SST file suitable for paleo (it can be one from previous coupled simulation or just take the generic 4X or 2X file depending on the pCO2 you will use) (l.31)
Modify the sea-ice file (amipbc_sic_1x1.nc) with a SIC file suitable for paleo (it can be one from previous coupled simulation or just take the generic 4X or 2X file depending on the pCO2 you will use) (l.32)
Uncomment the line relative to o2a.nc file (l.39) and modify it, with the o2a file you generated from the paleogeography

Generic SST and SIC files can be found here:

PATH/BC_CM5A2/LMDZ/40Ma_ICE/sst_bc_clim_2X.nc
PATH/BC_CM5A2/LMDZ/40Ma/no_sic_bc_clim.nc

You can also change some parameters in the PARAM/config.def_preind file:

CO2 (l.32):

co2_ppm = _AUTO_: DEFAULT = 0.280E+03

Solar constant (l.27) :

solaire = _AUTO_: DEFAULT = 1361.20

Orbital configuration (l. 20-24):

R_ecc = 0.06 
R_peri = 90 
R_incl = 24.5 

3. Launch the simulation

First you will need to reduce the time-wall (which is a 24h automatically), because this type of simulation will run quickly:

In the Job_SimulationName file replace 84600 by 1800 (l.10 : #MSUB -T 86400 # Wall clock limit (seconds))

Then submit the job


ccc_msub Job_SimulationName

LMDZOR

Once you have created the initial conditions with the ELC step you have to run an Atmosphere-Land Surface simulation

1. Generation of simulation directory

Copy the LMDZOR config.card in the $CCCWORKDIR/MODELE/modipsl/config/IPSLCM5A2 directory (you can also copy it from a previous simulation)
Modify the config.card :
- JobName= Name_Experiment [example : LMDZOR-SimulationNAme)]
- DateBegin=1854-01-01
- DateEnd=1854-12-30
Create the directory [../../libIGCM/ins_job]

 
 cp EXPERIMENTS/LMDZOR/clim_pdControl/config.card .
 
 ../../libIGCM/ins_job

2. Simulation setup

Then you will have to modify the following variables in the boundary condition file COMP/lmdz.card

LMDZ_Physics=AP (l.9)
ConfType=preind (l.17)

Without Antarctic ice-sheet

In case you want to remove ice in Antarctica (and have compiled the code to do so), additional modification should be done for running the LMDZOR simulation : (If you want to run simulation WITH an ice-sheet on Antarctica, just skip this part and see below)

In your WORKDIR (ideally you would have already created a directory where you store all you boundary conditions - $WORKDIR/YOUR_BC_DIRECTORY - …), create a MOD-ETAT0-LMDZ/SimulationName directory
Copy the following files into it :
- /ccc/store/cont003/gen2212/UserName/IGCM_OUT/LMDZ/SimulationName/ATM/Output/Boundary/ELC-SimulationName_clim_limit.nc
- /ccc/store/cont003/gen2212/UserName/IGCM_OUT/LMDZ/SimulationName/ATM/Output/Restart/ELC-SimulationName_clim_start.nc
- /ccc/store/cont003/gen2212/UserName/IGCM_OUT/LMDZ/SimulationName/ATM/Output/Restart/ELC-SimulationName_clim_startphy.nc
You then have to modify those files to add some ice on the south pole grid point (this is mandatory for the ORCHIDEE model to run) :

Ncap2 -s «FLIC(9025)=1.» -s «FTER(9025)=0.» ELC-SimulationName_clim_startphy.nc ELC-SimulationName_clim_startphy_corr.nc
Ncap2 -s «FLIC(:,9025)=1.» -s «FTER(:,9025)=0.» ELC-SimulationName_clim_limit.nc ELC-SimulationName_clim_limit_corr.nc

Then you need to specified boundary conditions files from the corresponding ELC simulation (l.53-54) and specifity the path for corresponding ELC start file as well as for the newely created startphy and limit files as below

[InitialStateFiles]
List=   ($STOREDIR/IGCM_OUT/LMDZ/ELC-SimulationName/ATM/Output/Restart/ELC-SimulationName_clim_start.nc,    start.nc),\
        ($WORKDIR/YOUR_BC_DIRECTORY/MOD-ETAT0-LMDZ/SimulationName/ELC-SimulationName_clim_startphy_corr.nc, startphy.nc)
        
[BoundaryFiles]
List=()
ListNonDel= ($WORKDIR/YOUR_BC_DIRECTORY/MOD-ETAT0-LMDZ/SimulationName/ELC-SimulationName_clim_limit_corr.nc, limit.nc),\

With a Antarctic Ice-sheet

You need to specified boundary conditions files from the corresponding ELC simulation (l.53-54) :

either specify CREATE=ELC-SimulationName (l.12) (Put the name of the ELC simulation you have done juste before) and be sure that the l.53-58 uses the CREATE variable to define the path. Or simply give the complete path to the start, starphy and limit files as below

[InitialStateFiles]
List=   ($STOREDIR/IGCM_OUT/LMDZ/ELC-SimulationName/ATM/Output/Restart/ELC-SimulationName_clim_start.nc,    start.nc),\
        ($STOREDIR/IGCM_OUT/LMDZ/ELC-SimulationName/ATM/Output/Restart/ELC-ELC-SimulationName_clim_startphy.nc, startphy.nc)
        
[BoundaryFiles]
List=()
ListNonDel= ($STOREDIR/IGCM_OUT/LMDZ/ELC-SimulationName/ATM/Output/Boundary/ELC-SimulationName_clim_limit.nc, limit.nc),\

For all types of simulation

Then you will have to modify the following variables in the boundary condition file COMP/orchidee.card

Modify the soil file (soils_param.nc), with a soil parameter file that has the correct geography (l.14)
Modify the routing file (routing.nc), with the new routing file (l.15)
Modify the Plant Functional Type file (PFTmap.nc) with the PTF file that has the correct geography (l.16)

You can also change some parameters in the PARAM/config.def_preind file :

CO2 (l.32):

co2_ppm = _AUTO_: DEFAULT = 0.280E+03

Solar constant (l.27) :

solaire = _AUTO_: DEFAULT = 1361.20

Orbital configuration (l. 20-24):

R_ecc = 0.06 
R_peri = 90 
R_incl = 24.5 

3. Launch the simulation


ccc_msub Job_SimulationName

Coupled Model

Once you have the 1 year-length LMDZOR simulation you can now run a coupled simulation. But before being able to launch it you will need to create restart files for the OASIS coupler.

Create file for OASIS

If it does not exist create a directory on your $CCCWORKDIR where you will generates the files ($CCCWORKDIR/BC_IPSLCM5A2) then download the CPLRESTART routines using a svn.

The CPLRESTART directory should contains 5 files :

README.txt
FillOceRestart.py is used to add missing variables in the OASIS restarts
Nemo.py is used with FillOceRestart.py
CreateRestartAtm4Oasis.bash is used to create atmosphere restart for OASIS
CreateRestartOce4Oasis.bash is used to create ocean restart for OASIS

In most of the case you will only need to create restart for the atmosphere :

Copy the histmth.nc file from the corresponding LMDZOR simulation
Extract the last month with nco
Run the CreateRestartAtm4Oasis.bash script
Move the files you generated in a directory spectific to you simulation

#Download the useful scripts

  mkdir $CCCWORKDIR/BC_IPSLCM5A2
  svn co http://forge.ipsl.jussieu.fr/igcmg/svn/TOOLS/CPLRESTART CPLRESTART

#Create atmospheric restart for OASIS

  cd CPLRESTART
  cp $STOREDIR/IGCM_OUT/LMDZOR/PROD/clim/SimulationName/ATM/Output/MO/SimulationName_xxxx_xxxx_histmth.nc .

  ncks -d time_counter,-1,-1 Nom_fichier_histmth.nc Nom_fichier_histmth_last_month.nc
  
# You need to modify the netcdf-hdf5 package otherwise it will not work (careful, this may be depreciated following recent updates on Irene)

  module load netcdf-c/4.3.3.1
  #module load netcdf/4.3.3.1_hdf5_parallel # Version for XIOS
  
  bash ./CreateRestartAtm4Oasis.bash Nom_fichier_histmth_last_month.nc
  
  mkdir SimulationName

  mv add_dim.nco create_flxat.nco flxat_LMD9695_maskFrom_ORCA2.3.nc icbrg_LMD9695_maskFrom_ORCA2.3.nc icshf_LMD9695_maskFrom_ORCA2.3.nc lonlat2xyz.nco      
 SimulationName_xxxx_xxxx_histmth.nc lonlat2xyz.nco SimulationName

You will use the flxat_LMD9695_maskFrom_Unknown.nc file late to setup the coupled simulation.

1. Generation of simulation directory

Copy coupled-model config.card in the $CCCWORKDIR/MODELE/modipsl/config/IPSLCM5A2 directory (you can also copy it from previous coupled simulation)
Modify the config.card :
- JobName= Name_Experiment [example : CPL-SimulationNAme)]
- CalendarType=360d [Choose leap years (leap) or no leap years (noleap) or 360 days-long years (360d = the one we usually use for paleo simulations)]
- DateBegin=1855-01-01
- DateEnd=4855-12-30 [This will fix the length of the simulation, we usually run coupled simulatios for at least 3,000 years]
Create the directory [../../libIGCM/ins_job]

 
cp EXPERIMENTS/IPSLCM/piControl/config.card .
 
 ../../libIGCM/ins_job

2. Simulation setup

You can still modify the config.card :

PeriodLength = 1Y
Restart : In case of standard coupled simulation you will only restart the components related to LMDZOR (LMDZ, SRF, MBG) so set the Restart = field to ‘y’ and then specify the path of the related simulation as in the following example. For all the other component let the Restart = field to ‘n’.

Example:

#D-- ATM -
[ATM]
WriteFrequency="1M"
# If config_Restarts_OverRule == 'n' next 4 params are read
Restart= y
# Last day of the experience used as restart for this component if Restart=y
RestartDate=1854-12-30
#D- Define restart simulation name for all components
RestartJobName=LMDZOR_SimulationName
#D- Path Server Group Login
RestartPath=$STOREDIR/IGCM_OUT/LMDZOR/PROD/clim

PackFrequency=10Y (l.184)
TimeSeriesFrequency=NONE (l.187)
SeasonalFrequency=100Y [Gives you the number of years that will be average in the SE outputs, usually we set up this field to 100Y] (l.190)

If you do not run the code on Irene but on Jean-Zay or other super-computer you may need to modyfile the number of processor in the _Executable part (be careful in case you do that you will need to modify the jpni, jpnj and jpnij PARAM/namelist_ORCA2cfg accordingly)

Modify the boundary conditions files for the atmosphere in COMP/lmdz.card

LMDZ_Physics=AP (l.9)
ConfType=preind (l.14)
LMDZ_NMC_monthly=n (l.44)
Replace Post_1M_histmthNMC and Post_1M_paramLMDZ_phy by NONE (l.100-101)

(histmthNMC.nc,    ${R_OUT_ATM_O_M}/${PREFIX}_1M_histmthNMC.nc,    NONE),    \
(paramLMDZ_phy.nc, ${R_OUT_ATM_O_M}/${PREFIX}_1M_paramLMDZ_phy.nc, NONE), \

Then you will have to modify the following variables in the boundary condition file COMP/orchidee.card

Modify the soil file (soils_param.nc), with a soil parameter file that has the correct geography (l.14)
Modify the routing file (routing.nc), with the new routing file (l.15)
Modify the Plant Functional Type file (PFTmap.nc) with the PTF file that has the correct geography (l.16)

Modify the boundary conditions files for the Ocean in COMP/opa.card

K1rowdrg.nc, M2rowdrg.nc, chlorophyll_surface_40Ma.nc, runoffs_ORCA2_depths.nc, sali_ref_clim_monthly.nc, coordinates.nc and mask_itf.nc are usually standard files you use in all the simulation (for Cenozoic simulation at least (?), except if you generate new tides files for example) and can be found in PATH/BC_CM5A2/NEMO/40Ma/filename.nc
sss_data.nc, sst_data.nc, data_1m_potential_temperature_nomask.nc and data_1m_salinity_nomask.nc are also standardized files (?)
bathy_meter.nc, ahmcoef.nc, subbasins.nc, geothermal_heating.nc are files you need to generates from paleogeography you use.
Replace Post_1D files by NONE (l. 61-62)

# For example 

(${config_UserChoices_JobName}_1d_grid_T.nc, ${R_OUT_OCE_O_D}/${PREFIX}_1D_grid_T.nc     , NONE),\

In the COMP/pisces.card

Replace Post_1D_bioscalar by NONE (l.52)

(${config_UserChoices_JobName}_1d_bioscalar.nc     , ${R_OUT_MBG_O_M}/${PREFIX}_1D_bioscalar.nc , NONE)

In stomate.card

Replace Post_1M_stomate_history.nc and Post_1M_stomate_ipcc_history by NONE (l.28)

[OutputFiles]
List=   (stomate_history.nc,      ${R_OUT_SBG_O_M}/${PREFIX}_1M_stomate_history.nc,      NONE),    \
        (stomate_ipcc_history.nc, ${R_OUT_SBG_O_M}/${PREFIX}_1M_stomate_ipcc_history.nc, NONE)

You also need to modify the COMP/oasis.card with the file you created from the corresponding LMDZOR simulation. [If it does not remind you something, you may be have missed this step here]

Specify the flatx and sstoc files. The sstoc file should correspond to the SST file you used in the previous ELC step. You can also create it using specific script in case you want to restart the ocean from an existing simulation.

Generic SST files can be found here:

PATH/BC_PALEOIPSL/COUPLER/40Ma-ICE-SL/sstoc_2X.nc

[InitialStateFiles]
List=   ($WORKDIR/CPLRESTART/SimulationName/flxat_LMD9695_maskFrom_Unknown.nc, flxat.nc), \
        (PATH/sstoc_2X.nc, sstoc.nc)

Specify the grids,masks,areas and MOZAIC-related files (l.15-21)

Example:

[BoundaryFiles]
List=   ()
ListNonDel= ($WORKDIR/IGCM/CPL/IPSLCM5A2/PALEORCA2.SimulationNamexLMD9695/grids.nc, grids.nc),\

Then in PARAM/field_def_nemo-opa.xml:

Then in PARAM/namelist_ORCA2_cfg. cp_cfg is the grid you use (orca2 or paleorca), rn_rdt is the timestep of the ocean, and jpni, jpnj and jpnij are the distribution of processor (have to correspond with the number of processors you setup in the config.card)

   cp_cfg      =  "paleorca"               !  name of the configuration
   
   rn_rdt      = 4800     !  time step for the dynamics (and tracer if nn_acc=0)
   
   jpni        =   4       !  jpni   number of processors following i (set automatically if < 1)
   jpnj        =  15       !  jpnj   number of processors following j (set automatically if < 1)
   jpnij       =  60       !  jpnij  number of local domains (set automatically if < 1)

You can also change some parameters in the PARAM/config.def_preind file :

CO2 (l.32):

co2_ppm = _AUTO_: DEFAULT = 0.280E+03

Solar constant (l.27) :

solaire = _AUTO_: DEFAULT = 1361.20

Orbital configuration (l. 20-24):

R_ecc = 0.06 
R_peri = 90 
R_incl = 24.5 

3. Launch the simulation

You need to change the number of year that will be done during one run (that can last up to 24h). In the Job_SimulationName file, change the period number (l.76). Usually we setup it to 60 or 70 years.

#D- Number of execution in one job
PeriodNb=60

Then you can finally launch your simulation


ccc_msub Job_SimulationName

Restarting from an existing simulation

Normal restart

Update bathymetry and restart

In some case you may want to do small bathymetry modification but you do not want to restart your simulation from scratch (because it will take to long). In this case you can (sometimes ?) re-generate salinity and temperature field from an existing simulation with similare paleogeography and use them as boundary conditions for the new simulation.

Modify the bathymetry locally using your favorite tool. Be sure you keep the variable names and dimension as in the initial file.
Extract salinity (so) and temperature (tethao) variables from the gridT.nc output of the simulation you want to restart from

ncks -v so SimulationName_gridT.nc SimulationName_gridT_so.nc 
ncks -v thetao SimulationName_gridT.nc SimulationName_gridT_thetao.nc 

Regenerate the temperature and salinity fields using Create_thetao.f90, Create_so.f90 and Create_thetao_so.ksh scripts. Before running them you need to read the comments insides and modify the files path inside.
Use the newly-created files in the PARAM/opa.card

Then you need to regenerate restart files for OASIS (both atmosphere and ocean) and use them in the PARAM/oasis.card

In most of the case you can restart the LMDZOR-related components (LMDZ, SRF, SBG) in the config.card and specify the path from the coupled simulation you restart from.

Useful tips

1. Where to find/store boundary conditions

Most of the time boundary conditions from a simulation can be find in user workdir withtin the BC_IPSLCM5A2 or BC_PALEOIPSL directory, classified by model component and by simulation (or at list it should !!).

2. (Normal) crash when you launch your 1st simulation ever

Check in the Job_SimulationName you did not make any mistake in the path of boundary conditions (in this case the error message is usually : ‘xxx.nc does not exist’)
Useful bash command if grep -ir error . It can help you track ‘error’ or ‘E R R O R’ or other key_word that may help you (maybe to find the bug)
