Detailed Description

2D Aspect Ratios Metric Class

Member Function Documentation

void compute ( double  atts[] ) const

virtual

Calculate scaled R/r and R/l.

Parameters

atts[]

R/r placed in atts[0], R/l in atts[1]

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 quadrilateral.

Implements Metric.
