Function Documentation

cs_lagr_new()

void cs_lagr_new	(	cs_lagr_particle_set_t *	particles,
		cs_lnum_t	n_faces,
		const cs_lnum_t	face_ids[],
		const cs_lnum_t	face_particle_idx[]
	)

Inject a series of particles at random positions on given faces.

The fluid velocity and other variables and attributes are computed here.

Parameters

[in,out]	particles	pointer to particle set
[in]	n_faces	number of faces in zone
[in]	face_ids	ids of faces in zone
[in]	face_particle_idx	starting index of added particles for each face in zone

cs_lagr_new_particle_init()

void cs_lagr_new_particle_init	(	const cs_lnum_t	particle_range[2],
		int	time_id,
		const cs_real_t	visc_length[]
	)

Initialization for new particles.

The fluid velocity seen is computed here.

Parameters

[in]	particle_range	start and past-the-end ids of new particles for this zone and class
[in]	time_id	associated time id (0: current, 1: previous)
[in]	visc_length	viscous layer thickness (size: number of mesh boundary faces)

cs_lagr_new_v()

void cs_lagr_new_v	(	cs_lagr_particle_set_t *	particles,
		cs_lnum_t	n_cells,
		const cs_lnum_t	cell_ids[],
		const cs_lnum_t	cell_particle_idx[]
	)

Inject a series of particles at random positions on given cells.

Warning

Currently works only for tri and quadrangular faces.

The fluid velocity and other variables and attributes are computed here.

Parameters

[in,out]	particles	pointer to particle set
[in]	n_cells	number of cells in zone
[in]	cell_ids	ids of cells in zone
[in]	cell_particle_idx	starting index of added particles for each cell in zone
