Mesh extrusion.

Function Documentation

cs_mesh_extrude()

void cs_mesh_extrude	(	cs_mesh_t *	m,
		const cs_mesh_extrude_vectors_t *	e,
		bool	interior_gc
	)

Extrude mesh boundary faces in the normal direction.

Extrusion is defined on selected boundary faces, and the number of layers for each associated vertex may be (slightly) variable, to account for cluttered areas where extrusion may be constrained, or more complex extrusions.

Parameters

[in,out]	m	mesh
[in]	e	extrusion vector definitions
[in]	interior_gc	if true, maintain group classes of interior faces previously on boundary

cs_mesh_extrude_constant()

void cs_mesh_extrude_constant	(	cs_mesh_t *	m,
		bool	interior_gc,
		cs_lnum_t	n_layers,
		double	thickness,
		double	expansion_factor,
		cs_lnum_t	n_faces,
		const cs_lnum_t	faces[]
	)

Extrude mesh boundary faces in the normal direction by a constant thickness.

Parameters

[in,out]	m	mesh
[in]	interior_gc	if true, maintain group classes of interior faces previously on boundary
[in]	n_layers	number of layers
[in]	thickness	extrusion thickness
[in]	expansion_factor	geometric expansion factor for extrusion refinement
[in]	n_faces	number of selected boundary faces
[in]	faces	list of selected boundary faces (0 to n-1), or NULL if no indirection is needed

cs_mesh_extrude_face_info_create()

cs_mesh_extrude_face_info_t* cs_mesh_extrude_face_info_create

(

const cs_mesh_t *

m

)

Create a mesh extrusion face information structure.

Parameters

[in]

m

mesh

Returns

pointer to new mesh extrusion face information structure.

cs_mesh_extrude_face_info_destroy()

void cs_mesh_extrude_face_info_destroy

(

cs_mesh_extrude_face_info_t **

efi

)

Destroy a mesh extrusion face information structure.

Parameters

[in,out]

efi

pointer to pointer to mesh extrusion face information.

cs_mesh_extrude_set_info_by_zone()

void cs_mesh_extrude_set_info_by_zone	(	cs_mesh_extrude_face_info_t *	efi,
		int	n_layers,
		double	distance,
		float	expansion_factor,
		const cs_lnum_t	n_faces,
		const cs_lnum_t	face_ids[]
	)

Set face extrusion information by zone.

Parameters

[in,out]	efi	mesh extrusion face information
[in]	n_layers	number of layers for selected faces
[in]	distance	extrusion distance for selected faces (if < 0, absolute value used as multiplier for boundary cell thickness)
[in]	expansion_factor	expansion factor for selected faces
[in]	n_faces	number of selected faces
[in]	face_ids	ids of selected faces, or NULL

cs_mesh_extrude_vectors_create()

cs_mesh_extrude_vectors_t* cs_mesh_extrude_vectors_create

(

const cs_mesh_extrude_face_info_t *

efi

)

Create and build a mesh extrusion vectors definition.

Extrusion vectors will be computed based on the provided extrusion face information structure. If no such structure is provided, an empty structure is returned.

Parameters

[in]

efi

mesh extrusion face information, or NULL

Returns

pointer to created mesh extrusion vectors definition.

cs_mesh_extrude_vectors_destroy()

void cs_mesh_extrude_vectors_destroy

(

cs_mesh_extrude_vectors_t **

e

)

Destroy a mesh extrusion vectors definition.

Parameters

[in,out]

e

pointer to pointer to mesh extrusion vectors definition.
