◆ operator()() [1/2]

virtual void BCFunction::operator()	(	FArrayBox &	a_state,
		const Box &	a_valid,
		const ProblemDomain &	a_domain,
		Real	a_dx,
		bool	a_homogeneous
	)

pure virtual

Computes values of a solution, $\phi$ , on ghost cells. These ghost values impose the boundary condition represented by the BCFunction object.

Parameters

a_state	The values of $\phi$ on the box given by a_valid.
a_valid	The box on which the boundary condition is to be imposed.
a_domain	The problem domain on which this boundary condition is imposed.
a_dx	The grid spacing.
a_homogeneous	If set to true, ghost values are computed for a homogeneous boundary condition. This is useful for multigrid solves.

Implemented in ConstBCFunction.

Referenced by operator()(), ~BCFunction(), and BCValueFunction::~BCValueFunction().

◆ operator()() [2/2]

virtual void BCFunction::operator()	(	FArrayBox &	a_state,
		const Box &	a_valid,
		const ProblemDomain &	a_domain,
		Real	a_dx,
		const DataIndex &	a_index,
		bool	a_homogeneous
	)

inlinevirtual

Computes the values of $\phi$ on ghost cells specifying a data index. By default, this calls the version of the method without a DataIndex.

Parameters

a_state	The values of $\phi$ on the box given by a_valid.
a_valid	The box on which the boundary condition is to be imposed.
a_domain	The problem domain on which this boundary condition is imposed.
a_dx	The grid spacing.
a_index	A DataIndex that can be used in the calculation.
a_homogeneous	If set to true, ghost values are computed for a homogeneous boundary condition. This is useful for multigrid solves.

◆ setTime()

virtual void BCFunction::setTime ( const Real & a_time )

inlinevirtual

Sets the time associated with this boundary condition. By default, this method does nothing, so this aspect of BCFunction can be ignored for time-independent boundary conditions.

Parameters

a_time The time to be passed to the boundary condition.
