Member Function Documentation

virtual void PhysIBC::define ( const ProblemDomain a_domain,
const Real a_dx 
) [virtual]

Define the object.

Parameters:
a_domain  problem domain index space
a_dx  grid spacing

virtual PhysIBC* PhysIBC::new_physIBC (  )  [pure virtual]

Factory method - this object is its own factory.

Return a pointer to a new PhysIBC object with m_isDefined = false (i.e., its define() must be called before it is used).

Implemented in AdvectTestIBC, ExplosionIBC, RampIBC, and WaveIBC.

virtual void PhysIBC::initialize ( LevelData< FArrayBox > &  a_U  )  [pure virtual]

Set up initial conditions.

Parameters:
a_U  conserved variables

Implemented in AdvectTestIBC, ExplosionIBC, RampIBC, and WaveIBC.

virtual void PhysIBC::primBC ( FArrayBox a_WGdnv,
const FArrayBox a_Wextrap,
const FArrayBox a_W,
const int &  a_dir,
const Side::LoHiSide a_side,
const Real a_time 
) [pure virtual]

Set boundary primitive values.

Parameters:
a_WGdnv  primitive variables at face centers; this routine replaces values along boundary faces of domain
a_Wextrap  extrapolated primitive variables to a_side of cells in direction a_dir (cell-centered data)
a_W  primitive variables at start of time step (cell-centered data)
a_dir  normal direction of the domain where boundary condition fluxes needed
a_side  side of the domain where boundary condition fluxes needed
a_time  physical time of the problem, for time-varying boundary conditions

Implemented in AdvectTestIBC, ExplosionIBC, RampIBC, and WaveIBC.

virtual void PhysIBC::setBdrySlopes ( FArrayBox a_dW,
const FArrayBox a_W,
const int &  a_dir,
const Real a_time 
) [pure virtual]

Set boundary slopes.

The boundary slopes in a_dW are already set to one-sided difference approximations. If this function doesn't change them, they will be used for the slopes at the boundaries.

Parameters:
a_dW  face-centered differences of primitive variables
a_W  primitive variables at start of time step (cell-centered data)
a_dir  normal direction of faces
a_time  physical time of the problem, for time-varying boundary conditions

Implemented in AdvectTestIBC, ExplosionIBC, RampIBC, and WaveIBC.

virtual void PhysIBC::artViscBC ( FArrayBox a_F,
const FArrayBox a_U,
const FArrayBox a_divVel,
const int &  a_dir,
const Real a_time 
) [pure virtual]

Adjust boundary fluxes to account for artificial viscosity.

Parameters:
a_F  face-centered flux, to be adjusted on boundary
a_U  cell-centered conserved variables
a_divVel  face-centered divergence of cell-centered velocity
a_dir  normal direction of faces
a_time  physical time of the problem, for time-varying boundary conditions

Implemented in AdvectTestIBC, ExplosionIBC, RampIBC, and WaveIBC.

virtual void PhysIBC::getBoundaryFaces ( Box a_boundaryBox,
const Box a_dataFaceBox,
const int &  a_dir,
const Side::LoHiSide a_side 
) [virtual]

This function is called by primBC() to get boundary faces of a Box.

Parameters:
a_boundaryBox  face-centered box of boundary faces to fill in; subbox of a_dataFaceBox
a_dataFaceBox  entire face-centered box
a_dir  normal direction of faces
a_side  side of the domain where boundary faces needed
