Function Documentation

◆ cs_user_les_inflow_advanced()

void cs_user_les_inflow_advanced	(	const cs_zone_t *	zone,
		cs_real_3_t	vel_l[],
		cs_real_6_t	rij_l[],
		cs_real_t	eps_l[]
	)

Definition of mean velocity, Reynolds stresses and dissipation rate for each boundary face of the given synthetic turbulence inlet.

Accurate definition of mean velocity, Reynolds stresses and dissipation rate for each boundary face of the given synthetic turbulence inlet

Rij components are ordered as usual: XX, YY, ZZ, XY, YZ, XZ

Arrays are pre-initialized before this function is called (see cs_user_les_inflow_define).

vel_l[face_id][coo_id] = vel_r[coo_id]

rij_l[face_id][0] = 2./3. * k_l rij_l[face_id][1] = 2./3. * k_l rij_l[face_id][2] = 2./3. * k_l rij_l[face_id][3] = 0 rij_l[face_id][4] = 0 rij_l[face_id][5] = 0

eps_l[face_id] = eps_r

Parameters

[in]	zone	pointer to associated boundary zone
[in,out]	vel_l	velocity a zone faces
[in,out]	rij_l	reynods stresses at zone faces
[in,out]	eps_l	reference turbulent dissipation

◆ cs_user_les_inflow_define()

void cs_user_les_inflow_define ( void )

Define parameters of synthetic turbulence at LES inflow.

◆ cs_user_les_inflow_update()

void cs_user_les_inflow_update	(	const cs_zone_t *	zone,
		cs_real_t	vel_r[3],
		cs_real_t *	k_r,
		cs_real_t *	eps_r
	)

Update of the characteristics of a given synthetic turbulence inlet.
