Detailed Description

IBC for simple Velocity advection (solid wall) boundary conditions.

This IBC sets normal component of velocities to the prescribed value (normally 0) at physical boundaries, and uses extrapolation to set tangential velocities.

Constructor & Destructor Documentation

VelIBC::VelIBC ( )

Null constructor.

VelIBC::VelIBC ( const Real & a_gamma,

const Real & a_ambientDensity,

const Real & a_deltaDensity,

const int & a_pressure,

const RealVect & a_center,

const Real & a_size,

const RealVect & a_velocity

)

Constructor which defines parameters used by Fortran routines.

VelIBC::~VelIBC ( ) [inline]

Destructor.

Member Function Documentation

const RealVect& VelIBC::advectionVel ( ) const

void VelIBC::advectionVel ( const RealVect & a_advVel )

set velocity

void VelIBC::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

)

Set boundary fluxes.

Real VelIBC::getNormalWallVel ( int a_dir,

Side::LoHiSide a_hiLo

) const

access boundary value

Real VelIBC::getSlopeValue ( int a_dir,

Side::LoHiSide a_hiLo

) const

access slope value

void VelIBC::initialize ( LevelData< FArrayBox > & a_U )

Set up initial conditions.

PhysIBC* VelIBC::new_physIBC ( )

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) and m_isFortranCommonSet set to value of m_isFortranCommonset in the current (factory) object.

int VelIBC::probType ( ) const

accessor

void VelIBC::probType ( const int a_probtype )

set problem type

void VelIBC::setBdrySlopes ( FArrayBox & a_dW,

const FArrayBox & a_W,

const int & a_dir,

const Real & a_time

)

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.
