Typedef Documentation

◆ dombounds

typedef std::array<std::array<double, 3>, 2> tetgen::dombounds

Type defining domain boundaries.

Simple short hand for a matrix of 2*3 doubles.

Definition at line 40 of file tetgenrsvs.hpp.

Function Documentation

◆ GenerateInternalPoints()

void tetgen::voronoi::GenerateInternalPoints	(	const mesh &	meshin,
		int	nLevels,
		tetgen::io_safe &	tetinPts
	)

Generate points inside volume cells of a mesh.

Parameters

[in]	meshin	The input mesh
[in]	nLevels	The number of layers of points in each cell.
	tetinPts	A tetgen io object which can be passed directly to tetrahedralize ast he fourth input.

Definition at line 1176 of file tetgenrsvs.cpp.

◆ ProjectRay()

template<class T , class V >

double tetgen::internal::ProjectRay	(	int	count,
		const tetgen::dombounds &	boundBox,
		const T &	dir,
		const V &	orig,
		double	minDist = `0.0`
	)

Project voronoi diagram rays to the bounding Box.

Parameters

[in]	count	number of coordinates
[in]	boundBox	The bounds of the domain (array<array<double,3>,2>)
[in]	dir	vector with direction (pointing in)
[in]	orig	The origin of the ray
[in]	minDist	The minimum allowable stretch distance

Template Parameters

T	type of `dir`: an iterable of size `count`
V	type of `orig`: an iterable of size `count`

Returns: Distance along the ray at which the boundBox is encountered.

◆ RSVSVoronoiMesh()

std::vector< int > tetgen::RSVSVoronoiMesh	(	const std::vector< double > &	vecPts,
		mesh &	vosMesh,
		mesh &	snakMesh,
		tetgen::apiparam &	inparam
	)

Genrates Snaking and VOS RSVS meshes from the voronoi diagram of a set of points.

Parameters

[in]	vecPts	a vector of input points (3 coordinate) followed by a target volume fraction. Vecpts is a 1D vector with 4 values per point.
	vosMesh	The vos mesh
	snakMesh	The snaking mesh
	inparam	The tetgen interface parameter at input.

Returns: Returns the mapping of the original points to the snake mesh volumes.

Definition at line 876 of file tetgenrsvs.cpp.

◆ SnakeToSU2()

void tetgen::SnakeToSU2	(	const snake &	snakein,
		const std::string &	fileName,
		tetgen::apiparam &	inparam
	)

Genrates an SU2 mesh file from a snake.

Uses tetgen to generate a volume mesh around a snake and outputs it to the SU2 format.

Parameters

[in]	snakein	A snake which needs to be meshed
[in]	fileName	The file name
	inparam	tetgen interface parameter object. Used to define boundary growth rate and element sizes.

Definition at line 1017 of file tetgenrsvs.cpp.

◆ SU2()

void tetgen::output::SU2	(	const char *	fileName,
		const tetgenio &	tetout
	)

 Ouputs a tetgen io object to an SU2 mesh file.

 File format: https://su2code.github.io/docs/Mesh-File/

 @param      fileName  is a string with the path to the target mesh

fileName

Parameters

tetout is tetgenio object (safe)

Exceptions

invalid_argument if fileName cannot be opened.

Definition at line 413 of file tetgenrsvs.cpp.

◆ TET2MESH()

mesh tetgen::output::TET2MESH ( tetgen::io_safe & tetout )

Translates a tetgen output to the RSVS native mesh format.

Parameters

tetout the tetgenio object containing a mesh to be translated to the native RSVS mesh format.

Returns: mesh object containing the translated grid.

Exceptions

invalid_argument if tetout was generated without passing the neighbour flag to tetgen (-nn)
