Detailed Description

Class to encapsulate the operations of ghost-cell boundary conditions.

BoxGhostBC is a class which encapsulates the operations of ghost-cell boundary conditions at a single face. If the solution is phi and the face normal direction is x, the boundary conditions usually used can be expressed as A*phi + B*dphi/dx = C. The derived class provides a function to to fill A B and C. These functions are only meant to be called by DomainGhostBC.

Member Function Documentation

virtual void BoxGhostBC::applyBCs (  const Box &    a_bcbox, FArrayBox &    a_state, const FArrayBox &    a_neumfac, const FArrayBox &    a_dircfac, const FArrayBox &    a_inhmval, Real    a_dx )  const [protected, virtual]

Actually applies the boundary conditions defined by the values in a_neumfac, a_dircfac, and a_inhmval to a_state in the region defined by a_bcBox (which should be the appropriate ghost cells) Reimplemented in BoxEdgeBC.

virtual void BoxGhostBC::applyHomogeneousBCs (  FArrayBox &    a_state, const ProblemDomain &    a_domain, Real    a_dx )  const [protected, virtual]

Apply the homogeneous form of the boundary conditions to a_state along the boundary of a_domain. Reimplemented in BoxEdgeBC, ExtrapBC, HOExtrapBC, NoOpBC, ReflectBC, and ReflectOddBC.

virtual void BoxGhostBC::applyHomogeneousBCs (  FArrayBox &    a_state, const Box &    a_domain, Real    a_dx )  const [protected, virtual]

Apply the homogeneous form of the boundary conditions to a_state along the boundary of a_domain. (Deprecated function -- use ProblemDomain instead of a Box to represent the domain) Reimplemented in BoxEdgeBC, ExtrapBC, HOExtrapBC, NoOpBC, ReflectBC, and ReflectOddBC.

virtual void BoxGhostBC::applyInhomogeneousBCs (  FArrayBox &    a_state, const ProblemDomain &    a_domain, Real    a_dx )  const [protected, virtual]

Apply the inhomogeneous form of the boundary conditions to a_state along the boundary of a_domain. Reimplemented in BoxEdgeBC, ExtrapBC, HOExtrapBC, NoOpBC, ReflectBC, and ReflectOddBC.

virtual void BoxGhostBC::applyInhomogeneousBCs (  FArrayBox &    a_state, const Box &    a_domain, Real    a_dx )  const [protected, virtual]

Apply the inhomogeneous form of the boundary conditions to a_state along the boundary of a_domain. (Deprecated function -- use ProblemDomain instead of a Box to represent the domain) Reimplemented in BoxEdgeBC, ExtrapBC, HOExtrapBC, NoOpBC, ReflectBC, and ReflectOddBC.

void BoxGhostBC::define (  int    a_dir, Side::LoHiSide    a_sd, const Interval &    a_comps )  [protected]

Full define function Reimplemented in BoxEdgeBC, and NoOpBC.

void BoxGhostBC::define (  int    a_dir, Side::LoHiSide    a_sd )  [protected]

Sets interval to be (0,0) Reimplemented in BoxEdgeBC, and NoOpBC.

virtual void BoxGhostBC::fillBCValues (  FArrayBox &    a_neumfac, FArrayBox &    a_dircfac, FArrayBox &    a_inhmval, Real    a_dx, const ProblemDomain &    a_domain )  const [protected, pure virtual]

Pure-virtual Worker function to fill arrays which define the boundary condition. Essentially, if the boundary condition is represented as A*phi + B*dphi/dn = C, then a_dircfac is A, a_neumfac is B, and a_inhmval is C. Implemented in InflowVelBC, BoxEdgeBC, edgeDirichletBC, ExtrapBC, HOExtrapBC, NoOpBC, ReflectBC, ReflectOddBC, and NeumannBC.

virtual void BoxGhostBC::fillBCValues (  FArrayBox &    a_neumfac, FArrayBox &    a_dircfac, FArrayBox &    a_inhmval, Real    a_dx, const Box &    a_domain )  const [protected, pure virtual]

Deprecated function -- use ProplemDomain version instead Implemented in InflowVelBC, BoxEdgeBC, edgeDirichletBC, ExtrapBC, HOExtrapBC, NoOpBC, ReflectBC, ReflectOddBC, NormalInflowVelBC, and NeumannBC.

virtual BoxGhostBC* BoxGhostBC::new_boxghostbc (    )  const [protected, pure virtual]

Virtual constructor workaround. Implemented in InflowVelBC, BoxEdgeBC, edgeDirichletBC, ExtrapBC, HOExtrapBC, NoOpBC, ReflectBC, ReflectOddBC, NormalInflowVelBC, and NeumannBC.
