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 (    )

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 )  [virtual]

Apply artificial viscosity at the boundary. The default implementation of this currently does nothing. Reimplemented in RampIBC.

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::fluxBC (  FArrayBox &    a_F, const FArrayBox &    a_W, const FArrayBox &    a_Wextrap, const int &    a_dir, const Side::LoHiSide &    a_side, const Real &    a_time )  [pure virtual]

Set boundary fluxes. Implemented in IdealMHDIBC, ExplosionIBC, GaussianIBC, RampIBC, SineIBC, and WaveIBC.

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

Set up initial conditions. Implemented in IdealMHDIBC, ExplosionIBC, GaussianIBC, RampIBC, SineIBC, and WaveIBC.

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 IdealMHDIBC, ExplosionIBC, GaussianIBC, RampIBC, SineIBC, and WaveIBC.

void PhysIBC::operator= (  const PhysIBC &    a_input )  [inline, private]

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, GaussianIBC, RampIBC, SineIBC, and WaveIBC.
