cs_cf_boundary_analytical_flux()

void cs_cf_boundary_analytical_flux	(	const cs_lnum_t	f_id,
		const cs_real_t *	val_ext_en,
		const cs_real_t *	val_ext_p,
		const cs_real_3_t *	val_ext_v
	)

Computes the analytical flux at the boundary for Euler and Energy.

The Euler equations used to compute the flux are:

Parameters

[in]	f_id	face id
[in]	val_ext_en	Dirichlet value for the total energy
[in]	val_ext_p	Dirichlet value for the pressure
[in]	val_ext_v	Dirichlet value for the velocity

cs_cf_boundary_rusanov()

void cs_cf_boundary_rusanov	(	const cs_lnum_t	f_id,
