Typedef Documentation

◆ BCFunc

typedef void(* BCFunc) (FArrayBox &a_state, const Box &a_valid, const ProblemDomain &a_domain, Real a_dx, bool a_homogeneous)

function interface for ghost cell boundary conditions of AMRPoissonOp. If you are using Neumann or Dirichlet boundary conditions, it is easiest to use the functions provided.

◆ BCValueFunc

typedef void(* BCValueFunc) (Real *a_pos, int *a_dir, Side::LoHiSide *a_side, Real *a_value)

given pos [x,y,z] position on center of cell edge int dir direction, x being 0 int side -1 for low, +1 = high, fill in the a_values array

◆ doNothingBC()

void doNothingBC	(	FArrayBox &	a_state,
		const Box &	a_valid,
		const ProblemDomain &	a_domain,
		Real	a_dx,
		bool	a_homogeneous
	)

For use with pure periodic BC.

◆ ConstDiriNeumBC()

RefCountedPtr<BCFunction> ConstDiriNeumBC	(	const IntVect &	a_loSideType,
		const RealVect &	a_loSideValue,
		const IntVect &	a_hiSideType,
		const RealVect &	a_hiSideValue
	)

A helper function to produce the needed object for constant Dirichlet/Neumann on all the faces. The return value can be passed to anything expecting a BCFunction/BCHolder.

"a_loSideType/a_hiSideType" specify the type of boundary condition in a given direction by having the enter corresponding to the direction set to 0 for Neumann or 1 for Dirichlet (on the low or high side, respectively). "a_loSideValue/a_hiSideValue" specify the (constant) value for boundary condition specified above.

For example, in 2D if "a_loSideType" = (1,0), "a_hiSideType" = (1,1), "a_loSideValue" = (0.0,1.0) and "a_hiSideValue" = (0.0,0.0) then the boundary conditions are:

   Low  side x:  Dirichlet = 0.0
   Low  side y:  Neumann   = 1.0
   High side x:  Dirichlet = 0.0
   High side y:  Dirichlet = 0.0
