Function Documentation

cs_mesh_location_add()

int cs_mesh_location_add	(	const char *	name,
		cs_mesh_location_type_t	type,
		const char *	criteria
	)

Define a new mesh location.

So as to define a subset of mesh entities of a given type, an optional selection criteria may be given.

Parameters

[in]	name	name of location to define
[in]	type	type of location to define
[in]	criteria	selection criteria for associated elements, or NULL

Returns

id of newly defined created mesh location

cs_mesh_location_add_by_func()

int cs_mesh_location_add_by_func	(	const char *	name,
		cs_mesh_location_type_t	type,
		cs_mesh_location_select_t *	func,
		void *	input
	)

Define a new mesh location with an associated selection function.

So as to define a subset of mesh entities of a given type, a pointer to a selection function may be given.

This requires more programming but allows finer control than selection criteria, as the function has access to the complete mesh structure.

Parameters

[in]	name	name of location to define
[in]	type	type of location to define
[in]	func	pointer to selection function for associated elements, or NULL
[in,out]	input	pointer to optional (untyped) value or structure.

Returns

id of newly defined created mesh location

cs_mesh_location_add_by_union()

int cs_mesh_location_add_by_union	(	const char *	name,
		cs_mesh_location_type_t	type,
		int	n_ml_ids,
		const int *	ml_ids,
		bool	complement
	)

Define a new mesh location.

So as to define a subset of mesh entities of a given type, a list of ids related to existing mesh locations may be given

Parameters

[in]	name	name of location to define
[in]	type	type of location to define
[in]	n_ml_ids	number of mesh location ids
[in]	ml_ids	list of mesh location ids
[in]	complement	take the complement of the selected entities if true

Returns

id of newly created mesh location

cs_mesh_location_build()

void cs_mesh_location_build	(	cs_mesh_t *	mesh,
		int	id
	)

Associate mesh locations with a mesh.

If mesh_id is negative, all defined mesh locations are associated (which is useful for the common case where only one mesh is present). If mesh_id is non-negative, only the location with the matching id is associated (which may be useful when multiple meshes are defined).

The number of elements are computed based on the underlying mesh, and element lists are built for mesh subset locations.

Parameters

[in]	mesh	pointer to associated mesh structure
[in]	id	id of mesh location

cs_mesh_location_finalize()

void cs_mesh_location_finalize

(

void

)

cs_mesh_location_get_elt_ids()

const cs_lnum_t* cs_mesh_location_get_elt_ids

(

int

id

)

Get a mesh location's element ids.

This function may only be used with a given location if cs_mesh_location_set_explicit_ids has been used to indicate explicit ids are needed for this location.

Parameters

[in]

id

id of mesh location

Returns

pointer to elements array (0 to n-1 numbering).

This function may only be used with a given location if cs_mesh_location_set_explicit_ids has been used to indicate explicit ids are needed for this location type.

Parameters

[in]

id

id of mesh location

Returns

pointer to elements array (0 to n-1 numbering).

cs_mesh_location_get_elt_ids_try()

const cs_lnum_t* cs_mesh_location_get_elt_ids_try

(

int

id

)

Get a mesh location's element ids, if present.

An array of element ids is returned if the location is a subset of a main main location type, and NULL is returned when the id array would map to the identity function (i.e. {0, 1, 2, ..., n_elts-1}).

Parameters

[in]

id

id of mesh location

Returns

pointer to elements array (0 to n-1 numbering).

cs_mesh_location_get_elt_list()

const cs_lnum_t* cs_mesh_location_get_elt_list

(

int

id

)

Get a mesh location's elements list, if present.

A list of elements is defined if the location is a subset of a main location type.

Deprecated:

Use cs_mesh_location_get_elt_ids_try or cs_mesh_location_get_elt_ids instead.

Parameters

[in]

id

id of mesh location

Returns

pointer to elements array (0 to n-1 numbering).

cs_mesh_location_get_explicit_ids()

bool cs_mesh_location_get_explicit_ids

cs_mesh_location_initialize()

void cs_mesh_location_initialize

(

void

)

Initialize mesh location API.

By default, 7 mesh locations are built, matching the 7 first values of the cs_mesh_location_type_t enum: CS_MESH_LOCATION_NONE for global values, CS_MESH_LOCATION_CELLS for the cells of the (default) global mesh, CS_MESH_LOCATION_INTERIOR_FACES and CS_MESH_LOCATION_BOUNDARY_FACES for its faces, and CS_MESH_LOCATION_VERTICES for its vertices. CS_MESH_LOCATION_FACES and a placeholder for CS_MESH_LOCATION_EDGES are also added for CDO discretizations.

Locations should then be built once the global mesh is complete, and its halo structures completed.

cs_mesh_location_n_locations()

int cs_mesh_location_n_locations

(

void

)

Return number of mesh locations defined.

Returns

number of mesh locations defined

cs_mesh_location_set_explicit_ids()
