Allow nonhydrostatic version of FV3

[ta440]

What is the feature/what would you like to discuss?

Allow FV3 to be run using its nonhydrostatic solver, instead of the default hydrostatic one. As the vertical velocity is now a prognostic variable, this requires the initialisation of a nonzero initial w field.

Part of this enhancement would require modifications to the src/dynamics/fv3/dyn_comp.F90 file that is located in the CAM_FV3_interface github repository.

Is there anyone in particular you want to be part of this conversation?

No response

Will this change (regression test) answers?

No

Will you be implementing this enhancement yourself?

Yes
