      cellCoBlended: New surfaceInterpolation scheme based on CoBlended using the cell-based Courant number
      
          This scheme is equivalent to the CoBlended scheme except that the Courant
          number is evaluated for cells using the same approach as use in the
          finite-volume solvers and then interpolated to the faces rather than being
          estimated directly at the faces based on the flux.  This is a more
          consistent method for evaluating the Courant number but suffers from the
          need to interpolate which introduces a degree of freedom.  However, the
          interpolation scheme for "Co" is run-time selected and may be specified in
          "interpolationSchemes" and "localMax" might be most appropriate.
      
          Example of the cellCoBlended scheme specification using LUST for Courant
          numbers less than 1 and linearUpwind for Courant numbers greater than 10:
          \verbatim
          divSchemes
          {
              .
              .
              div(phi,U)  Gauss cellCoBlended 1 LUST grad(U) 10 linearUpwind grad(U);
              .
              .
          }
      
          interpolationSchemes
          {
              .
              .
              interpolate(Co) localMax;
              .
              .
          }
          \endverbatim
