Detailed Description

3D Aspect Ratios Metric Class

Definition at line 107 of file Geometric_Metrics_3.h.

Constructor & Destructor Documentation

Aspect_Metric_3 ( )

inline

Initialize a 3D Aspect Metric.

Member Function Documentation

void compute ( double  atts[] ) const

virtual

Calculate the metric value on this element.

Parameters

atts[]

Computed value(s) placed here.

Note that R/r and R/l are only implemented for simplical elements. This method will return -1 for both metrics if used on a hexahedron.

Implements Metric.
