◆ count()

template<size_t NG>

size_t AMP::Mesh::TriangleHelpers::count ( const std::vector< std::array< int, NG+1 > > & tri )

Count the number of unique triangles.

◆ createTriangles()

template<size_t NG, size_t NP>

void AMP::Mesh::TriangleHelpers::createTriangles	(	const std::vector< std::array< std::array< double, NP >, NG+1 > > &	tri_list,
		std::vector< std::array< double, NP > > &	vertices,
		std::vector< std::array< int, NG+1 > > &	triangles,
		double	tol
	)

Create triangles/vertices from a set of triangles specified by their coordinates.

◆ estimateMeshSize()

size_t AMP::Mesh::TriangleHelpers::estimateMeshSize ( std::shared_ptr< const MeshParameters > params )

Estimate Mesh size.

◆ generate() [1/2]

template<size_t NG, size_t NP = 3>

std::shared_ptr< AMP::Mesh::Mesh > AMP::Mesh::TriangleHelpers::generate	(	const std::vector< std::array< std::array< double, NP >, NG+1 > > &	triangles,
		const AMP_MPI &	comm,
		const std::string &	name,
		double	tol = `1e-12`,
		bool	splitDomain = `true`,
		int	loadBalanceMethod = `1`
	)

Generate a triangle mesh from local triangle coordinates.

Create a triangle mesh from the local triangle coordinates. Note: rank 0 must contain all data, other ranks "may" contain copies

Parameters

triangles	List of triangles (rank 0 should contain all triangles)
comm	Communicator to use
tol	Relative tolerance to determine if two points are the same
name	Name of mesh
splitDomain	Split multi-domain objects into seperate meshes (returning a multimesh)
loadBalanceMethod	Load balance method to use (only used if splitting multi-domain)

◆ generate() [2/2]

std::shared_ptr< AMP::Mesh::Mesh > AMP::Mesh::TriangleHelpers::generate ( std::shared_ptr< const MeshParameters > params )

Generate a triangle mesh (or multi-mesh) from parameters.

◆ generateGeom()

std::shared_ptr< AMP::Mesh::Mesh > AMP::Mesh::TriangleHelpers::generateGeom	(	std::shared_ptr< AMP::Geometry::Geometry >	geom,
		const AMP_MPI &	comm,
		double	resolution
	)

Generate a triangle mesh (or multi-mesh) from a geometry.

◆ generateSTL()

std::shared_ptr< AMP::Mesh::Mesh > AMP::Mesh::TriangleHelpers::generateSTL ( std::shared_ptr< const AMP::Mesh::MeshParameters > params )

◆ maxProcs()

size_t AMP::Mesh::TriangleHelpers::maxProcs ( std::shared_ptr< const MeshParameters > params )

◆ readSTL()

std::vector< std::array< std::array< double, 3 >, 3 > > AMP::Mesh::TriangleHelpers::readSTL	(	const std::string &	filename,
		double	scale
	)
