[MITgcm-support] Offline model help

[Martin Losch]

Hi Tongya,

where you able to figure this out? I am sorry that no-one replied. Your error message means that there’s something wrong in one of you namelist files.
Maybe you can keep and inspect “scratch1.000000019” This is a copy of one of your namelist files, where apparently (or rather “likely”) the termination character of one of the namelists is incorrect. If that’s the case you can set your termination character from “&” to “/“ by adding DEFINES=“$DEFINES -DNML_TERMINATOR” (or similar) in your build options file.
