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.

Member Function Documentation

initialize()

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

virtual

Set up initial conditions.

shouldn't be in this function – we're required to

Implements PhysIBC.

new_physIBC()

PhysIBC * VelIBC::new_physIBC ( )

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

Implements PhysIBC.

setBdrySlopes()

void VelIBC::setBdrySlopes ( FArrayBox &  a_dW, const FArrayBox &  a_W, const int &  a_dir, const Real &  a_time  )

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.

Implements PhysIBC.
