Detailed Description

Importer for tetrahedral meshes in notation which was used in [1].

If the check for the Jacobian gives an error, the order of the triangles and vertices has to be changed.

Deprecated:

Use Import3dMesh instead

Constructor & Destructor Documentation

Import3DTetMesh()

concepts::Import3DTetMesh::Import3DTetMesh	(	const std::string	coord,
		const std::string	elms,
		const std::string	dirichlet,
		const bool	leftHand = false
	)

Constructor. Takes 3 files with coordinates of the vertices, node numbers of the elements (tetrahedrons) and node numbers of the triangles which have homogeneous Dirichlet bc.

Parameters

coord	Filename for the coordinates. Format: <node> <x> <y> <z> For instance: 1 1.0 1.0 1.0 2 0.0 0.5 2.0
elms	Filename for the elements. Format: <nr> <node 1> <node 2> <node 3> <node 4>
dirichlet	Filename for triangles with homogeneous Dirichlet bc. Format: <nr> <node 1> <node 2> <node 3>
leftHand	Ordering of the node numbers

info()

virtual std::ostream & concepts::Import3DTetMesh::info ( std::ostream &  os ) const

protectedvirtual

Returns information in an output stream.

Reimplemented from concepts::Mesh.

ncell()

virtual uint concepts::Import3DTetMesh::ncell ( ) const

inlinevirtual

Returns the number of cells in the mesh.

Implements concepts::Mesh.

scan()

virtual Scan3 * concepts::Import3DTetMesh::scan ( )

inlinevirtual

Returns a scanner over the cells of the mesh.

Postcondition

The scanner must be deleted after usage. This has to be done by the user.

Implements concepts::Mesh3.
