Detailed Description

The procedures for computing MAC velocities and edge states with MOL does not involve time derivatives. All slope computations use second-order limited slopes as described in [sec:slopes].

ComputeEdgeState()

void MOL::ComputeEdgeState	(	amrex::Box const &	a_bx,
		AMREX_D_DECL(amrex::Array4< amrex::Real > const &xedge, amrex::Array4< amrex::Real > const &yedge, amrex::Array4< amrex::Real > const &zedge)	,
		amrex::Array4< amrex::Real const > const &	q,
		int	ncomp,
		AMREX_D_DECL(amrex::Array4< amrex::Real const > const &umac, amrex::Array4< amrex::Real const > const &vmac, amrex::Array4< amrex::Real const > const &wmac)	,
		amrex::Box const &	domain,
		amrex::Vector< amrex::BCRec > const &	bcs,
		amrex::BCRec const *	d_bcrec_ptr,
		bool	is_velocity
	)

Compute upwinded face-centered states by extrapolating cell-centered values in SPACE ONLY.

Parameters

[in]	a_bx	Current grid patch
[in,out]	xedge	Array4 containing x-edges, starting at component of interest
[in,out]	yedge	Array4 containing y-edges, starting at component of interest
[in,out]	zedge	Array4 containing z-edges, starting at component of interest
[in]	q	Array4 of state, starting at component of interest
[in]	ncomp	Number of components to work on
[in]	umac	x-Face velocities.
[in]	vmac	y-Face velocities.
[in]	wmac	z-Face velocities.
[in]	domain	Problem domain.
[in]	bcs	Vector of boundary conditions
[in]	d_bcrec_ptr	BCRec
[in]	is_velocity	Indicates a component is velocity so boundary conditions can be properly addressed. The header hydro_constants.H defines the component positon by [XYZ]VEL macro.

Compute upwinded FC states by extrapolating CC values in SPACE ONLY. This is NOT a Godunov type extrapolation: there is NO dependence on time! The resulting FC states are computed at the CENTROID of the face.

ExtrapVelToFaces()

void MOL::ExtrapVelToFaces	(	const amrex::MultiFab &	vel,
		AMREX_D_DECL(amrex::MultiFab &umac, amrex::MultiFab &vmac, amrex::MultiFab &wmac)	,
		const amrex::Geometry &	a_geom,
		amrex::Vector< amrex::BCRec > const &	h_bcrec,
		const amrex::BCRec *	d_bcrec
	)

Compute upwinded FC velocities by extrapolating CC values in SPACE ONLY.

Parameters

vel	The cell-centered velocity field
umac	x-component of velocity on centroid of x-face
vmac	y-component of velocity on centroid of y-face
wmac	z-component of velocity on centroid of z-face
a_geom	Geometry object at this level
h_bcrec	Host version of BCRec
d_bcrec	Device version of BCRec
