aspectRatio()

static double aspectRatio ( const ASMbase &  patch, int  iel  )

static

Compute the aspect ratio of a cell.

The aspect ratio is defined as the longest edge divided by the shortest edge

computeAspectRatios()

bool MeshUtils::computeAspectRatios	(	std::vector< double > &	elmAspects,
		const SIMbase &	model,
		const Vector &	displacement = Vector()
	)

Compute element aspect ratios for a mesh.

Parameters

[out]	elmAspects	The element aspect ratios
[in]	model	The model holding the mesh
[in]	displacement	A displacement to apply to mesh coordinates

computeMeshSkewness()

bool MeshUtils::computeMeshSkewness	(	std::vector< double > &	elmSkewness,
		const SIMbase &	model,
		const Vector &	displacement = Vector()
	)

Compute element skewness for a mesh.

Parameters

[out]	elmSkewness	The element skewness values
[in]	model	The model holding the mesh
[in]	displacement	A displacement to apply to mesh coordinates

skewness()

static double skewness ( const ASMbase &  patch, int  iel  )

static

Compute the skewness of a cell.

The skewness measures the deviance from a regular cell in terms of angles
