Constructor & Destructor Documentation

◆ t8_geometry_occ() [1/2]

t8_geometry_occ::t8_geometry_occ	(	int	dim,
		const char *	fileprefix,
		const char *	name
	)

Constructor of the occ geometry with a given dimension.

The geometry is currently viable with quad/hex and triangle trees. Tets will be supported soon. The geometry uses as many vertices as the tree type has, as well as additional geometry information, which is extracted from a .brep file. The vertices are saved via the t8_cmesh_set_tree_vertices function. Since the internals of this geometry are finely tuned to the .brep file it is recommended to only use it with the t8_cmesh_readmshfile function.

Parameters

[in]	dim	The dimension of this geometry.
[in]	fileprefix	Prefix of a .brep file from which to extract an occ geometry.
[in]	name	The name to give this geometry.

◆ t8_geometry_occ() [2/2]

t8_geometry_occ::t8_geometry_occ	(	int	dim,
		const TopoDS_Shape	occ_shape,
		const char *	name
	)

Constructor of the occ geometry with a given dimension.

The geometry is currently viable with quad/hex and triangle trees. Tets will be supported soon. The geometry uses as many vertices as the tree type has, as well as additional geometry information, which is given via the occ_shape. The vertices are saved via the t8_cmesh_set_tree_vertices function. This constructor can be used in short scripts or in combination with a mesh generator, to omit the file IO of the t8_geometry_occ (int dim, const char *fileprefix, const char *name) constructor.

Parameters

[in]	dim	The dimension of this geometry.
[in]	occ_shape	Occ shape geometry.
[in]	name	The name to give this geometry.

◆ ~t8_geometry_occ()

virtual t8_geometry_occ::~t8_geometry_occ ( )

inlinevirtual

The destructor.

Clears the allocated memory.

	)		const

Converts the parameters of an occ edge to the corresponding parameters on an occ face.

[in]	num_face_nodes	The number of the face nodes of the evaluated element. Only needed for closed surface check, otherwise NULL.
[in]	edge_param	The parameter on the edge.
[in]	surface_param	The parameters of the surface nodes. When provided, there are additional checks for closed geometries. If there are no surface parameter to pass in to the function, you can pass NULL.
