ERROR: ANGLE is outside its expected range

[Riley]

When I submited one of the B1850 experiments, there was a special error. The solution in userguide is "Check the binary file for errors and resolution. The POP2 model may be reading bad data from the binary grid or topography file".

Error in cesm logs:

POP aborting...
ERROR: ANGLE is outside its expected range

------------------------------------------------------------------------
--------------------------------------------------------------------------
MPI_ABORT was invoked on rank 102 in communicator MPI_COMM_WORLD
with errorcode 0.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

Hi, did you ever find a solution to this? I am having the same issue.

Hi Marisa, I just saw this.
1) Firstly, I checked the value of ANGLE in forcing files. Make sure that the ocean/ice grid is normal. I found that the error wasn't from the forcing files. If your angle is normal, the error may come from the criterion of angle.
2) Secondly, I changed two .F90 files and added into the SourceMods. The criterion of angle was changed (grid.F90 in pop and ice_grid.F90 in cice). Then rebuilt it. It worked out.
I uploaded two attachments.
Hope this works for you.

Riley.
