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)

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 ExtrapBC, and HOExtrapBC.

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 ExtrapBC, and HOExtrapBC.

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 ExtrapBC, and HOExtrapBC.

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 ExtrapBC, and HOExtrapBC.

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

Full define function

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

Sets interval to be (0,0)

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 ExtrapBC, HOExtrapBC, 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 ExtrapBC, HOExtrapBC, and NeumannBC.

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

Virtual constructor workaround.

Implemented in ExtrapBC, HOExtrapBC, and NeumannBC.
