Below is a representative stencil for the distribution of the nodes and associated stencil.
Note that the nodes lie are 'volume centered' in the axial direction but still lie along the boundaries in the radial direction.
This governs the ability, or lack thereof, to use predefined boundary conditions.
For example, this stencil WILL directly interface with 'DynamicPipe' because that requires volume centered Q_flow and T values which this method satisfies.
