cs_boundary_conditions_error()

void cs_boundary_conditions_error	(	const int *	bc_flag,
		const char *	type_name
	)

Handling of boundary condition definition errors and associated output.

This function checks for errors, and simply returns if no errors are encountered. In case of error, it outputs helpful information so as to make it easier to locate the matching faces.

For each boundary face, bc_type defines the boundary condition type. As a convention here, zero values correspond to undefined types, positive values to defined types (with no error), and negative values to defined types with inconsistent or incompatible values, the absolute value indicating the original boundary condition type.

An optional label may be used if the error is related to another attribute than the boundary type, for appropriate error reporting.

Parameters

[in]	bc_flag	array of BC type ids
[in]	type_name	name of attribute in error, or NULL

cs_boundary_conditions_map()

ple_locator_t* cs_boundary_conditions_map	(	cs_mesh_location_type_t	location_type,
		cs_lnum_t	n_location_elts,
		cs_lnum_t	n_faces,
		const cs_lnum_t *	location_elts,
		const cs_lnum_t *	faces,
		cs_real_3_t *	coord_shift,
		int	coord_stride,
		double	tolerance
	)

Locate shifted boundary face coordinates on possibly filtered cells or boundary faces for later interpolation.

Parameters

[in]	location_type	matching values location (CS_MESH_LOCATION_CELLS or CS_MESH_LOCATION_BOUNDARY_FACES)
[in]	n_location_elts	number of selected location elements
[in]	n_faces	number of selected boundary faces
[in]	location_elts	list of selected location elements (0 to n-1), or NULL if no indirection is needed
[in]	faces	list of selected boundary faces (0 to n-1), or NULL if no indirection is needed
[in]	coord_shift	array of coordinates shift relative to selected boundary faces
[in]	coord_stride	access stride in coord_shift: 0 for uniform shift, 1 for "per face" shift.
[in]	tolerance	relative tolerance for point location.

Returns

associated locator structure

cs_boundary_conditions_mapped_set()

void cs_boundary_conditions_mapped_set	(	const cs_field_t *	f,
		ple_locator_t *	locator,
		cs_mesh_location_type_t	location_type,
		int	normalize,

		const cs_lnum_t *	faces,

	)

Set mapped boundary conditions for a given field and mapping locator.

Parameters

[in]	f	field whose boundary conditions are set
[in]	locator	associated mapping locator, as returned by cs_boundary_conditions_map.
[in]	location_type	matching values location (CS_MESH_LOCATION_CELLS or CS_MESH_LOCATION_BOUNDARY_FACES)
[in]	normalize	normalization option: 0: values are simply mapped 1: values are mapped, then multiplied by a constant factor so that their surface integral on selected faces is preserved (relative to the input values) 2: as 1, but with a boundary-defined weight, defined by balance_w 3: as 1, but with a cell-defined weight, defined by balance_w
[in]	interpolate	interpolation option: 0: values are simply based on matching cell or face center values 1: values are based on matching cell or face center values, corrected by gradient interpolation
[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
[in]	balance_w	optional balance weight, or NULL
[in]	nvar	number of variables requiring BC's
[in,out]	rcodcl	boundary condition values
