So I think I found a solution. The strange temperature behavior at pRefCell was not coming from the temperature equation, but from the pressure equation. During the pressure solution, the value of...

Bump. To try and provide some more info, wrote out the location of the pressure reference cell, and then applying:

TEqn.setReference(pRefCell,T.internalField()[pRefCell]);

to see if it's...

To try to offer up some more information...

The error comes during the TEqn.solve() step. If you look at the temperature at the cell "pRefCell" you can see it changing wildly after the solution. ...

I'm seeing the same issue, except the mesh isn't axisymmetric. The mesh is a cube of hexahedral cells, looking at a buoyancy flows (solving for piezometric pressure "pd" instead of "p = pd +...
