Quality

The criterion Quality is calculated differently for different element types.

  • Tri and Tetra

    The quality is calculated as the minimum ratio of height to base length of each side (normalized to 1).

  • Quad

    The quality is calculated as the Determinant, as described in Determinant (2x2x2 stencil).

  • Hexa

    The quality is a weighted diagnostic between Determinant (between -1 and 1), Max Orthogls (normalized between -1 and 1; if deviation from orthogonality is greater than 90 degrees, then the normalized value will be smaller than 0) and Max Warpgls (normalized between 0 and 1; warpage of 0 degrees is 1, warpage of 180 degrees is 0). The minimum of the 3 normalized diagnostics will be used.

  • Pyramid

    The quality is calculated as the determinant.

  • Prism

    The quality is calculated as the minimum of the Determinant and Warpage. Warpage is normalized to a factor between 0 and 1, where 90 degrees is 0, and 0 degrees is 1.
