Is code in model/esmf still being used?

[JessicaMeixner-NOAA]

@ErickRogers Are you or others still using code in model/esmf? Or is this obsolete code that can be removed?

[ErickRogers]

Jessica, We are using the ESMF interface wmesmfmd.ftn with COAMPS (v6.07) and Navy ESPC (v7.00.X) and we are still making changes there. I've never had any reason to look at the contents of /model/esmf/ so I don't know if the code there is compiled into the coupled model (COAMPS/ESPC) when ESMF is invoked, or if it is just vestigial code. I'm guessing it's the latter, since I can't find that code in the COAMPS distribution. Tim, can you confirm? I also cc Alex as the Navy ESPC ESMF SME. Erick

It was originally trying to run wmesmf but we haven't used it at EMC in several years, and I didn't know if you were still using it or not. If not, perhaps we can just delete? If you agree I can open a PR for it for possible deletion and see if anyone else says no?

[ErickRogers]

I might be confused now. Would this PR be to delete /model/src/wmesmfmd.F90 or /model/esmf/ or both?

[JessicaMeixner-NOAA]

Apologies this PR would only be to delete /model/esmf we will be keeping /model/src/wmesmfmd.F90

[JessicaMeixner-NOAA]

And that's only if you aren't using /model/esmf if you are, we will keep it.

[ErickRogers]

OK, let's proceed with your plan to open the PR. Tim is technically on leave (may or may not be checking email this week), so let's give him some time to chime in prior to completing the PR.

[JessicaMeixner-NOAA]

Sounds good. I will not merge the PR before hearing from Tim. It's okay to keep the code if it's actually being used, but if it's not it's always good to clean-up.

From Tim Campbell: "The model/esmf code was implemented for standalone testing of the esmf interface. The model/esmf code is no longer used and can be removed."
