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.

Remove all hierarchy dependent data allocated by initializeOperatorState().
Reimplemented from IBTK::GeneralOperator.

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