cs_rad_transfer_bc_coeffs()

void cs_rad_transfer_bc_coeffs	(	int	bc_type[],
		cs_real_t	vect_s[3],
		cs_real_t	ckmel[],
		cs_real_t	bpro_eps[],
		cs_real_t	w_gg[],

Boundary conditions for DO and P-1 models.

The coefap array stores the intensity for each boundary face, depending of the nature of the boundary (Dirichlet condition). The intensity of radiation is defined as the rate of emitted energy from unit surface area through a unit solid angle.

1/ Gray wall: isotropic radiation field.

which is the sum of the wall emission and reflecting flux (eps=1: black wall; eps=0: reflecting wall).

2/ Free boundary: condition to mimic infinite domain

Parameters

[in]	bc_type	boundary face types
[in]	vect_s	direction vector or nullptr
[in]	ckmel	Absoprtion coefficcient of the mixture gas-particules of coal or nullptr
[in]	bpro_eps	Boundary emissivity, or nullptr for solar radiation
[in]	w_gg	Weights of the i-th gray gas at boundaries
[in]	gg_id	number of the i-th grey gas
[out]	bc_coeffs	boundary conditions structure for intensity or P-1 model
