Hi Diane, OK, since your mesh is perfectly orthogonal, you don't need to use correct boundary conditions. Also the skewCorrected interpolation won't do anything and Gauss will be perfect for grad,...

Hi Diane, Does your mesh contain non-orthogonality and/or skewness? And do the boundary cells contain non-orthogonality? By default OpenFOAM sets boundary non-orthogonal corrections to zero, so...
