[MITgcm-support] STOP ABNORMAL END: S/R INI_PRESSURE

[kunal madkaiker]

Dear MITgcm Users,

I am trying to run MITgcm along West Coast of India, using a Curvilinear
grid.
I have given climatological profile of Temperature, Salinity and U,V
surface wind stress for Dec.

Model is unable to compute RMS-difference for hydrostatic pressure. I tried
to run model with
tRef and sRef values and it gave me result. So, I know problem may lie in
my temperature and
salinity files, but unable to figure out where exactly, since I am able to
list and plot these
netcdf files correctly.

I have also tried converting NaN values into -999.9 in the input files but
isnt helping.

I edited the ini_pressure.F source code and changed steps from 15 to 30 but
error persists.

Kindly assist with the error. Thanks in advance!
Please let me know if any additional information is required.
