[MITgcm-support] format of input files wrong in regional model with open boundary conditions?

[Jonny Williams]

Hi there

I am trying to get a regional model version of the MITgcm running but am
having a problem which I have been stuck on for the last few days.

I can seemingly compile my model successfully but at run time I get the
following error...

*PGFIO-F-253/unformatted read/unit=9/attempt to read non-existent record
(direct access).*
* File name = OBNu.bin    unformatted, direct access   record = 556*
* In source file mdsio_read_section.f, at line number 1851*

I do not understand this because my input file OBNu.bin is definitely
present in the run directory.

Line 1851 of mdsio_read_section.f is illustrated in bold, underlined font
in the snippet below...

Does anyone have any ideas about what the issue could be with this?

Many thanks!
