◆ modifyRhsForBcs()

void IBTK::LinearOperator::modifyRhsForBcs ( SAMRAI::solv::SAMRAIVectorReal< NDIM, double > &  y)
overridevirtualinherited

Before calling this function, the form of the vector y should be set properly by the user on all patch interiors on the range of levels covered by the operator. All data in this vector should be allocated. The user is responsible for managing the storage for the vectors.

Note
The operator MUST be initialized prior to calling modifyRhsForBcs.
See also
initializeOperatorState
Note
A default implementation evaluates y := y - A*0.

Reimplemented from IBTK::GeneralOperator.

◆ apply()

virtual void IBTK::GeneralOperator::apply ( SAMRAI::solv::SAMRAIVectorReal< NDIM, double > &  x,
SAMRAI::solv::SAMRAIVectorReal< NDIM, double > &  y 
)
pure virtualinherited

Before calling apply(), the form of the vectors x and y should be set properly by the user on all patch interiors on the specified range of levels in the patch hierarchy. The user is responsible for all data management for the quantities associated with the vectors. In particular, patch data in these vectors must be allocated prior to calling this method.

Parameters
xinput vector
youtput vector, i.e., \(y=F[x]\)

Conditions on Parameters:

  • vectors x and y must have same hierarchy
  • vectors x and y must have same structure, depth, etc.

In general, the vectors x and y cannot be the same.

Note
Subclasses may require that the operator be initialized prior to calling apply().

initializeOperatorState

Implemented in IBTK::PETScSNESJacobianJOWrapper, IBTK::PETScMFFDJacobianOperator, IBTK::PETScSNESFunctionGOWrapper, IBAMR::ConvectiveOperator, IBAMR::VCStaggeredStokesOperator, IBTK::PETScMatLOWrapper, IBTK::SCLaplaceOperator, IBTK::CCLaplaceOperator, and IBTK::VCSCViscousOperator.

◆ applyAdd()

virtual void IBTK::GeneralOperator::applyAdd ( SAMRAI::solv::SAMRAIVectorReal< NDIM, double > &  x,
SAMRAI::solv::SAMRAIVectorReal< NDIM, double > &  y,
SAMRAI::solv::SAMRAIVectorReal< NDIM, double > &  z 
)
virtualinherited

Before calling applyAdd(), the form of the vectors x, y, and z should be set properly by the user on all patch interiors on the specified range of levels in the patch hierarchy. The user is responsible for all data management for the quantities associated with the vectors. In particular, patch data in these vectors must be allocated prior to calling this method.

Parameters
xinput vector
yinput vector
zoutput vector, i.e., \(z=F[x]+y\)

Conditions on Parameters:

  • vectors x, y, and z must have same hierarchy
  • vectors x, y, and z must have same structure, depth, etc.

In general, the vectors x and y cannot be the same.

Note
Subclasses may require that the operator be initialized prior to calling applyAdd().
See also
initializeOperatorState
Note
A default implementation is provided which employs apply() and SAMRAI::solv::SAMRAIVectorReal::add().

Reimplemented in IBTK::PETScSNESJacobianJOWrapper, and IBTK::PETScMatLOWrapper.

◆ initializeOperatorState()

virtual void IBTK::GeneralOperator::initializeOperatorState ( const SAMRAI::solv::SAMRAIVectorReal< NDIM, double > &  in,
const SAMRAI::solv::SAMRAIVectorReal< NDIM, double > &  out 
)
virtualinherited

The vector arguments for apply(), applyAdd(), 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.

deallocateOperatorState
Parameters
ininput vector
outoutput vector
