- Face Validity
- Face validity is an area-weighted measure of the correctness of the face normals relative to their attached cell centroid. In a good quality cell, the face normals point away from the cell centroid. In a cell with bad face validity, one or more face normals point towards the attached cell centroid.

Values below 1.0 mean that some cell face normals point towards the centroid, indicating some form of concavity. Values of below 0.5 signify a negative volume cell.
