Using libIGCM library with ORCA2_LIM
Purposes:
- Document the using of libIGCM for NEMO, in configuration ORCA2_LIM
- Official documentation of libIGCM is :
Quick start guide:
30/10/2009 at this moment when downloading NEMO_IGCM default configuration is:
climatological run, with bulk clio forcing, with calendar type 360d and output frequency 1Y, without iom_put, with MONITORING, and ATLAS.
At the bottom of this page informations to switch
- interannual run, with bulk core forcing, with calendar type noleap and output frequency 1M, without iom_put, with MONITORING, and ATLAS.
- activate iom_put
- Define the following alias to use SVN :
alias svn_ano='svn co http://forge.ipsl.jussieu.fr/igcmg/svn/modipsl/trunk modipsl'
- Create and go into working directory :
mkdir TRY ; cd TRY
- Extract modipsl :
svn_ano
- Extract NEMO :
cd modipsl/util ./model NEMO_IGCM
- Choosing ORCA2_LIM configuration :
cd ../modeles/UTIL ./fait_config ORCA2_LIM
NOTE: in this moment NEMO_IGCM is downloading trunk NEMO (ongoing test on iom_put) but there is a bug on bottom friction.
To evoid this bug it is necessary to:
- comment lines in modipsl/modeles/NEMO/WORK/dommsk.F90:
ij0 = 115 ; ij1 = 115
ii0 = 145 ; ii1 = 146 ; fmask( mi0(ii0):mi1(ii1) , mj0(ij0):mj1(ij1) , 1:jpk ) = 4.0e0
ij0 = 116 ; ij1 = 116
ii0 = 145 ; ii1 = 146 ; fmask( mi0(ii0):mi1(ii1) , mj0(ij0):mj1(ij1) , 1:jpk ) = 4.0e0
- put in namelist rn_bfri1 = 0.e-4
- Install the makefiles :
cd ../../util ./ins_make
- Compile :
cd ../config/ORCA2_LIM gmake
- Submit Job :

To reduce computing time, if you don't use the ATLAS, you can put in namelist : ln_mskland=.false., because it is very expensive in term of computational time.
And also see useful remarks: https://forge.ipsl.jussieu.fr/nemo/wiki/private/libIGCM/suggestpage
If you want to switch from climatological to interannual see: https://forge.ipsl.jussieu.fr/nemo/wiki/private/libIGCM/change_BC
To activate iom_put see: https://forge.ipsl.jussieu.fr/nemo/wiki/private/libIGCM/iom_put
