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 [(γi-βi)/(180-βi), 1-γi/βi]
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:
This function is calculated across entity boundaries when adjacent entities are also selected for Examine.
