cs_mesh_location_select_t |
Function pointer to mesh location elements selection definition.
If non-empty and not containing all elements, a list of elements of the parent mesh belonging to the location should be allocated (using BFT_MALLOC) and defined by this function when called. This list's lifecycle is then managed by the mesh location object.
- Parameters
-
[in] | m | pointer to associated mesh structure. |
[in] | location_id | id of associated location. |
[out] | n_elts | number of selected elements |
[out] | elt_list | list of selected elements. |

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 |
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
Define a new mesh location with a 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 |
- Returns
- id of newly defined created mesh location
void cs_mesh_location_finalize |
( |
void |
| ) |
|
Finalize mesh location API.
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.
- Parameters
-
[in] | id | id of mesh location |
- Returns
- pointer to elements list (0 to n-1 numbering).
const cs_lnum_t* cs_mesh_location_get_n_elts |
( |
int |
id | ) |
|
Get a mesh location's number of elements.
A pointer to a array of 3 values is returned: 0: local number of elements 1: with standard ghost elements (if applicable) 2: with extended ghost elements (if applicable)
- Parameters
-
[in] | id | id of mesh location |
- Returns
- array of numbers of elements.
const char* cs_mesh_location_get_name |
( |
int |
id | ) |
|
Get a mesh location's name.
- Parameters
-
[in] | id | id of mesh location |
- Returns
- pointer to mesh location name
Get a mesh location's type.
- Parameters
-
[in] | id | id of mesh location |
- Returns
- mesh location type
void cs_mesh_location_initialize |
( |
void |
| ) |
|
Initialize mesh location API.
By default, 5 mesh locations are built, matching the 5 first values of the cs_mesh_location_type_t enum: CS_MESH_LOCATION_NONE for global values, CS_MESH_LOCCATION_CELLS for the cellsof 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.
Locations should then be built once the global mesh is complete, and its halo structures completed.
int cs_mesh_location_n_locations |
( |
void |
| ) |
|
Return number of mesh locations defined.
- Returns
- number of mesh locations defined
