[MITgcm-support] Issues at lateral boundary for a doubly periodic domain

[Takaya Uchida]

Dear MITgcm Support,

I’ve been trying to run a sweep of idealized doubly periodic flows but I am getting issues at the zonal boundaries of the domain.
I’ve prescribed the domain to have the depth everywhere of -2000m but MITgcm seems to think there’s a wall at the zonal extent of the domain. The meridional extents behave as expected being periodic.

I’ve attached a screenshot of a horizontal slice of zonal velocity along with the SIZE.h and data file.

I would appreciate any input on what I may be doing wrong.

Best,
Takaya
