Detailed Description

Class to enforce ghost-cell based boundary conditions.

This class holds a domain's worth of boxghostbcs, at least one for each face. The user adds BoxGhostBC-derived objects for each face to enforce boundary conditions. If the solution is phi and the face normal direction is x, the boundary conditions at a face may often be expressed as A*phi + B*dphi/dx = C. The class derived from BoxGhostBC provides a function to to fill A B and C. DomainGhostBC calls this function and fills the ghost cells outside the domain appropriately. Because BoxGhostBC operates on a component Interval, more than one BoxGhostBC per side is supported, to support the case where different components have different boundary conditions.

Member Function Documentation

void DomainGhostBC::applyHomogeneousBCs (  FArrayBox &    a_state, const ProblemDomain &    a_domain, Real    a_dx )  const

apply boundary conditions on all sides of state which abut domain edge

void DomainGhostBC::applyHomogeneousBCs (  FArrayBox &    a_state, const Box &    a_domain, Real    a_dx )  const

Deprecated function -- use ProblemDomain instead of a Box for the domain.

void DomainGhostBC::applyInhomogeneousBCs (  FArrayBox &    a_state, const ProblemDomain &    a_domain, Real    a_dx )  const

Apply boundary conditions on all sides of state which abut the domain edge *.

void DomainGhostBC::applyInhomogeneousBCs (  FArrayBox &    a_state, const Box &    a_domain, Real    a_dx )  const

Deprecated function -- use ProblemDomain instead of a Box for the domain.

bool DomainGhostBC::isBCDefined (  const int    a_dir, const Side::LoHiSide    a_side )  const [protected]

Returns true if this GhostBC is defined

const List<BoxGhostBC*>& DomainGhostBC::operator() (  int    a_direction, Side::LoHiSide    a_side )  const

Access function -- returns a reference to the BC on the given face.

DomainGhostBC& DomainGhostBC::operator= (  const DomainGhostBC &    a_dgbcin )

Assignment operator.

void DomainGhostBC::resetBoxGhostBC (  const int    a_dir, const Side::LoHiSide    a_side )  [protected]

Resets BC in the given direction and side to an unset state (deletes any existing BC's and returns to an empty list)

void DomainGhostBC::setBoxGhostBC (  const BoxGhostBC &    a_ghostBC )

Set boundary conditions at a face to those defined in a_ghostBC. Adds a_ghostBC to whatever BCs are already defined for the gviven side and face.
