Description

The Equi-Angular Skewness (Fidelity) examine metric is available when at least one block is selected for Examine. This metric is compatible with the Fidelity Equiangular Skewness metric.

For a given cell, the Equi-Angular Skewness at edge i is computed using the dihedral angle of the cell at that edge (γi) and the corresponding dihedral angle of the equivalent ideal cell at that edge (βi).

ESi = max [(γii)/(180-βi), 1-γii]

where:

ESi = Equi-Angular skewness considering dihedral angle at cell edge i
γi = Dihedral angle between the faces of the cell sharing edge i
βi = Dihedral angle between the faces of the equivalent ideal cell sharing edge i

The final equi-angular skewness of the cell is computed by taking the maximum of all the dihedral angles:

ES = max [ESi]

This function is calculated across entity boundaries when adjacent entities are also selected for Examine.
