template<class TPointType >

double Kratos::Tetrahedra3D4< TPointType >::VolumeToRMSEdgeLength ( ) const

inlineoverridevirtual

Calculates the volume to average edge length quality metric. Calculates the volume to average edge length quality metric. The average edge lenght is calculated using the RMS. This metric is bounded by the interval (0,1) being: 1 -> Optimal value 0 -> Worst value

\( \frac{V}{\sqrt{\frac{1}{6}\sum{A_{i}^{2}}}} \)

Returns: [description]

◆ VolumeToSurfaceAreaQuality()

template<class TPointType >

double Kratos::Tetrahedra3D4< TPointType >::VolumeToSurfaceAreaQuality ( ) const

inlineoverridevirtual

Calculates the volume to surface area quality metric. Calculates the volume to surface area quality metric. 1 -> Optimal value 0 -> Worst value

\( \frac{V^4}{(\sum{A_{i}^{2}})^{3}} \)

Returns: volume to surface quality.
