Detailed Description

Member Function Documentation

define()

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

Reimplemented in PhysMappedIBC.

new_physIBC()

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 WaveIBC, RampIBC, ExplosionIBC, PhysMappedIBC, and AdvectTestIBC.

initialize()

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

pure virtual

Set up initial conditions.

Parameters

a_U	conserved variables

Implemented in WaveIBC, RampIBC, ExplosionIBC, PhysMappedIBC, and AdvectTestIBC.

primBC()

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 WaveIBC, RampIBC, ExplosionIBC, PhysMappedIBC, and AdvectTestIBC.

setBdrySlopes()

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 PhysMappedIBC, WaveIBC, RampIBC, ExplosionIBC, and AdvectTestIBC.

artViscBC()

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 PhysMappedIBC, WaveIBC, RampIBC, ExplosionIBC, and AdvectTestIBC.

getBoundaryFaces()

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

operator=()
