Detailed Description

Physical/domain initial and boundary conditions.

Virtual base class through which a user specifies the initial and boundary conditions for a hyperbolic system of PDEs.


Constructor & Destructor Documentation

PhysIBC::PhysIBC  ) 
 

Constructor.

virtual PhysIBC::~PhysIBC  )  [virtual]
 

Destructor.


Member Function Documentation

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.

Implemented in ExplosionIBC, RotorMHDIBC, and WaveMHDIBC.

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

Define the object.

Set the problem domain index space and the grid spacing for this initial and boundary condition object.

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

Set up initial conditions.

Implemented in ExplosionIBC, RotorMHDIBC, and WaveMHDIBC.

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

Factory method - this object is its own factory.

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

Implemented in ExplosionIBC, RotorMHDIBC, and WaveMHDIBC.

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 fluxes.

Implemented in ExplosionIBC, RotorMHDIBC, and WaveMHDIBC.

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.

Implemented in ExplosionIBC, RotorMHDIBC, and WaveMHDIBC.
