Function Documentation

Calculate_Exact_Fluxes_CUDA()

template<int reconstruction, uint direction>

__global__ void Calculate_Exact_Fluxes_CUDA	(	Real const *	dev_conserved,
		Real const *	dev_bounds_L,
		Real const *	dev_bounds_R,
		Real *	dev_flux,
		int const	nx,
		int const	ny,
		int const	nz,
		int const	n_cells,
		Real const	gamma,
		int const	n_fields
	)

Exact Riemann solver based on the Fortran code given in Sec. 4.9 of Toro (1999).

Template Parameters

reconstruction	What kind of reconstruction to use, PCM, PLMC, etc. This argument should always be a member of the reconstruction::Kind enum, behaviour is undefined otherwise.
direction	The direction that the solve is taking place in. 0=X, 1=Y, 2=Z

Parameters

[in]	dev_bounds_L	The interface states on the left side of the interface
[in]	dev_bounds_R	The interface states on the right side of the interface
[out]	dev_flux	The output flux
[in]	n_cells	Total number of cells
[in]	n_ghost	Number of ghost cells on each side
[in]	n_fields	The total number of fields
