Quality/Determinant
 
1 Attachment(s)
Hi,

In ICEM documentation there is written that, for Hexa elements: "The quality is calculated as the Determinant, as described in Determinant (2x2x2 stencil)". But, fo my case, the parameter evaluations are different. Sobebody has an idea, why?

Thanks,
Batis

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.
