Error in MOM6 with custom mask tables #42

Description

@manodeep

(Copying the issue over from the om3-configs)

I am testing out different MOM6 layouts for the 25km IAF config. One of the layouts I tested was 60,48, but I got the following error immediately on startup (repeated across the PEs).

FATAL from PE   486: MPP_DEFINE_DOMAINS(mpp_compute_extent): domain extents must be positive definite.

This is the command that generated the above mask table:

./gen_masktable.sh -g /g/data/vk83/configurations/inputs/access-om3/mom/grids/mosaic/global.25km/2025.09.02/ocean_hgrid.nc -t /g/data/vk83/configurations/inputs/access-om3/share/grids/global.25km/2025.11.27/topog.nc -l 60 48

Other failing layouts (with the same error) are:

  • 60x60
  • 58x48
  • 64x48.

I have run MOM6 successfully (as part of the 25k IAF config) for other layouts that I have generated.
