31.1.1 Cell Values

ANSYS FLUENT stores most variables in cells. For postprocessing, the entire region contained within the cell has this value. A surface cell value is the value of the cell that has been intersected by a surface facet or line, or that contains a surface point. Since surface facets and lines are created from the intersection of isovalues and the existing mesh cells, this is a unique definition. Typically, the cell value on a boundary is the value in the cell adjacent to the boundary. For face-only functions like Wall Shear Stress, the cell value is the area-weighted average from the face values that define that cell as c0. This value is used for the cell values of postprocessing surfaces. But for boundary faces, the cell value actually displays / uses the exact face value.
