[MITgcm-support] Open boundary conditions for Internal Waves.

[Jeremy Miller]

Dear MITgcm forum,

Hope everyone's well. Following yesterday's email and reading Section
8.3.1.4.1 of the docs I attempted to change the file data.obcs myself,
because I wanted to move from the default grid to Nx ✕ Ny = 120 ✕ 60 .
Accordingly I changed data.obcs to

# Open-boundaries
 &OBCS_PARM01
 OB_Ieast = 60*-1,
 OB_Iwest = 60*1,
 OB_Jnorth = 120*-1,
 OB_Jsouth = 120*1,
 &

After running I get this error:

At line 2509 of file obcs_readparms.f (unit = 11, file =
'scratch1.000000000')
Fortran runtime error: Cannot match namelist object name c

Please, could you advise.

Best
Jeremy
