This merge increases the maximum Haney number (rx1: a measure of how steep and think ocean layer are) to 20 for global ocean initial conditions with ice-shelf cavities (wISC). This should be more similar to a z-star coordinate, which is not yet supported in MPAS-Ocean init mode.

Testing indicated that a Haney number of 20 caused crashes in the ECwISC mesh, so the maximum Haney number for that mesh has been set to 15 instead.

Checklist

  • Document (in a comment titled Testing in this PR) any testing that was used to verify the changes

Testing

The following meshes were successfully tested through the files_for_e3sm stage with a maximum Haney number of 20:

  • SOwISC12to60E3r1
  • WCwISC14to60E3r1
  • IcoswISC120E3r1
  • IcoswISC240E3r1
  • IcoswISC480E3r1 - files for E3SM failed but related to masking the Pacific MOC (i.e. unrelated to this PR).

The following mesh required a maximum Haney number of 15:

  • ECwISC30to60E3r1

The following mesh will be tested in a later PR:

  • ARRMwISC10to60E3r1
