Detailed Description

Class INSStaggeredWavePropConvectiveOperator is a concrete ConvectiveOperator that implements a convective operator based on the wave propagation method.

Class INSStaggeredWavePropConvectiveOperator computes the convective derivative of a cell-centered velocity field using the wave propagation method of Ketcheson and LeVeque.

Note
INSStaggeredWavePropConvectiveOperator currently only works in ADVECTIVE form.
Todo:
Implement a CONSERVATIVE form for the operator. This will involve writing a new Riemann solver for the flux.

Member Function Documentation

◆ deallocateOperatorState()

void IBAMR::INSStaggeredWavePropConvectiveOperator::deallocateOperatorState ( )
overridevirtual

Remove all hierarchy dependent data allocated by initializeOperatorState().

Note
It is safe to call deallocateOperatorState() when the operator state is already deallocated.
See also
initializeOperatorState

Reimplemented from IBTK::GeneralOperator.

◆ initializeOperatorState()

void IBAMR::INSStaggeredWavePropConvectiveOperator::initializeOperatorState ( const SAMRAI::solv::SAMRAIVectorReal< NDIM, double > &  in,
const SAMRAI::solv::SAMRAIVectorReal< NDIM, double > &  out 
)
overridevirtual

Compute hierarchy dependent data required for computing y=F[x] and z=F[x]+y.

The vector arguments for apply(), applyAdjoint(), etc, need not match those for initializeOperatorState(). However, there must be a certain degree of similarity, including

  • hierarchy configuration (hierarchy pointer and level range)
  • number, type and alignment of vector component data
  • ghost cell widths of data in the input and output vectors
Note
It is generally necessary to reinitialize the operator state when the hierarchy configuration changes.

It is safe to call initializeOperatorState() when the state is already initialized. In this case, the operator state is first deallocated and then reinitialized.

Conditions on arguments:

  • input and output vectors must have same hierarchy
  • input and output vectors must have same structure, depth, etc.

Call deallocateOperatorState() to remove any data allocated by this method.
