WRF with threed_cartesian?

Hi,
I appreciate your support of the DART software.

What's the issue?

I don't know whether this is a bug or a missing feature:
I tried to compile DART with WRF and threed_cartesian but received an error about non-existing VERTISUNDEF, VERTISSURFACE, VERTISHEIGHT, and so on. These names don't exist in location/threed_cartesian/location_mod.f90, but they are defined in location/threed_sphere/location_mod.f90.

Do you know if this is supposed to work? If not, it could be noted in the documentation. Can you estimate what's necessary to make it work?

Anything else we should know?

I used DART-v10.9.2.

I noticed that location/threed_cartesian/location_mod.f90 contained VERTISHEIGHT at some point: https://github.com/NCAR/DART/commit/f900c4d50bc39cb0b519ea7f45360dfa487bc8ad

My goal would be to use periodic horizontal coordinates for an idealized WRF limited area domain.

Thank you!

Start by reproducing the DART-v10.9.2 WRF build using the command line in cmdline.txt. Compare location/threed_cartesian/location_mod.f90 with location/threed_sphere/location_mod.f90 and review commit f900c4d50bc39cb0b519ea7f45360dfa487bc8ad. Done means establishing whether threed_cartesian is supported for WRF and either documenting the limitation or defining the required implementation scope.
