if and why mpp_get_boundary should be called when .not. bounded_domain

[TingLei-NOAA]

Dear UFS developers,
Would you tell me if and why the mpp_get_boundary should only be called when bounded_domain is not true (namely, global runs)?
From the codes itself, seems this should work for regional runs (bounded_domain=.true.). But, it was found there would be problems when it was used in jedi 's D-A wind conversion for fv3-lam (regional fv3). And in UFS dyn_core.F90, there is if( it==n_split .and. gridstruct%grid_type<4 .and. .not. gridstruct%bounded_domain) then ! Prevent accumulation of rounding errors at overlapped domain edges: call mpp_get_boundary(u, v, domain, ebuffery=ebuffer, & nbufferx=nbuffer, gridtype=DGRID_NE )
So, any clarification and explanation are appreciated.

Hello @TingLei-NOAA!
Were you able to get the answer to your question? If not, I can see if I can some answers for you!

@ShawnCebulaNOAA Yes. That will be great if some expert can give an answer on that. I am still trying to learn more about fms.
Thank you so much for your attention on this question.

@TingLei-NOAA is this problem solved? It was long time ago.

[TingLei-NOAA]

@RatkoVasic-NOAA Sure. The Jeid 's D-A wind conversions issue had been fixed by D. Holdaway with the help from R. Benson. I think this question could be closed. Thanks
