Function Documentation

cs_turbulence_rij()

void cs_turbulence_rij	(	cs_lnum_t	ncesmp,
		cs_lnum_t	icetsm[],
		int	itypsm[],
		cs_real_t	smacel[]
	)

Solve the for incompressible flows or slightly compressible flows for one time step.

Please refer to the model section of the theory guide for more informations, as well as the turrij section.

Parameters

[in]	ncesmp	number of cells with mass source term
[in]	icetsm	index of cells with mass source term
[in]	itypsm	mass source type for the variables
[in]	smacel	values of the variables associated to the mass source (for ivar=ipr, smacel is the mass flux) !

cs_turbulence_rij_clip()

void cs_turbulence_rij_clip

(

cs_lnum_t

n_cells

)

Clip the turbulent Reynods stress tensor and the turbulent dissipation (coupled components version).

Parameters

[in]

n_cells

number of cells

cs_turbulence_rij_clip_sg()

void cs_turbulence_rij_clip_sg	(	cs_lnum_t	n_cells,
		int	iclip
	)

Clip the turbulent Reynods stress tensor and the turbulent dissipation (segregated version)

Parameters

[in]	n_cells	number of cells
[in]	iclip	if 0, viscl0 is used; otherwise viscl is used.

cs_turbulence_rij_init_by_ref_quantities()

void cs_turbulence_rij_init_by_ref_quantities	(	cs_real_t	uref,
		cs_real_t	almax
	)

Initialize Rij-epsilon variables based on reference quantities.

If uref is not provided (0 or negative), values are set at a large negative value (-cs_math_big_r) to allow for later checks.

Parameters

[in]	uref	characteristic flow velocity
[in]	almax	characteristic macroscopic length of the domain

cs_turbulence_rij_solve_alpha()

void cs_turbulence_rij_solve_alpha	(	int	f_id,
		cs_real_t	c_durbin_l
	)

Solve the equation on alpha in the framework of the Rij-EBRSM model.

Also called for alpha of scalars for EB-DFM.

Parameters

[in]	f_id	field id of alpha variable
[in]	c_durbin_l	constant for the Durbin length !
