Detailed Description

template<int DIM>
class SAMRAI::xfer::RefineAlgorithm< DIM >

interpolate data (spatial and possibly temporal) from coarser levels
copy data from the same level of refinement
fill physical boundary conditions regions

Each data communication procedure generally consists of three parts: an algorithm, a schedule, and a patch strategy. The algorithm describes the patch data components and time and space interpolation operations, but is independent of the configuration of the patches in an AMR hierarchy.
Patch data items and their associated spatial and time interpolation operators are registered with an instantiation of this algorithm class.
To generate the communication dependencies for a particular patch hierarchy configuration, the algorithm creates a refine schedule based on the state of a given hierarchy and the information in the algorithm. The schedule can then perform the communication operations that move data to the destination patch level using the associated operators. User-defined operations (such as filling physical boundaries and special interpolation procedures) are provided through a refine patch strategy object.

In general, source data is copied into the designated scratch data for temporary processing. The scratch space must contain sufficient ghost cells to accommodate the stencil width of the given interpolation operators and any physical boundary data that must be filled. The scratch storage is copied into the destination data space at the end of the communication process.
Thus, copy operations between source, scratch, and destination patch data objects must be defined. In general, it is the user's responsibility to register valid operations with the refine algorithm so that the data communication can occur.

In general, the destination and scratch data components may be the same (assuming that the scratch component has a sufficient ghost cells width). The source and scratch components SHOULD NOT be the same, since the interiors of the source space would be changed by the use of the scratch data as temporary work space.

Note that each refine schedule created by a refine algorithm remains valid as long as the patches involved in the communication process do not change; thus, they can be used for multiple data communication cycles.

Typical usage of a refine algorithm to perform inter-patch communication on an AMR hierarchy involves four steps:

Construct a refine algorithm object.
Register refine operations with the refine algorithm. Using the registerRefine() methods(s), one provides source and destination patch data information, as well as time and space interpolation operators as needed. Two registerRefine() methods appear in this class; one supports time interpolation, one does not.
After all operations are registered with the algorithm, one creates a communication schedule using one of the createSchedule() methods. These methods are distinguished by the resulting data communication pattern (e.g., interpatch communication on a single level, between two different levels at the same grid resolution, interpolation of data between different AMR hierarchy levels, etc.) Note that when creating a communication schedule, a concrete instance of a RefinePatchStrategy<DIM> object may be required to supply physical boundary conditions as well as user-defined spatial data interpolation operations.
Invoke the fillData() method in the communication schedule to perform the data transfers.

User-defined interpolation operations can be written using the interfaces in RefinePatchStrategy for preprocessRefine() and postProcessRefine(). Users who use create these operations must note that all data that is to be used in such operations should be registered with the RefineAlgorithm using registerRefine(), whether or not the data is to be refined.

template<int DIM>

void SAMRAI::xfer::RefineAlgorithm< DIM >::registerRefine	(	const int	dst,
		const int	src,
		const int	scratch,
		tbox::Pointer< RefineOperator< DIM > >	oprefine,
		tbox::Pointer< VariableFillPattern< DIM > >	var_fill_pattern = `tbox::Pointer< BoxGeometryFillPattern< DIM > >()`
	)

Register a refine operation with the refine algorithm object. This routine does not support time interpolation. Data values will be moved from the source component to the destination component using scratch component as a temporary work space. The scratch component must have sufficient ghost cells to cover the required operator stencil width and any needed physical boundary ghost cells.

Parameters

dst	Integer destination patch data index to be filled on the destination level.
src	Integer source patch data index on the source level.
scratch	Integer patch data index used as a temporary work space.
oprefine	tbox::Pointer to refinement operator. This may be a null pointer. In this case, refinement must be handled by the refine patch strategy member functions. See the comments for RefinePatchStrategy<DIM>::preprocessRefine() and RefinePatchStrategy<DIM>::postprocessRefine().

		tbox::Pointer< TimeInterpolateOperator< DIM > >	optime,
		tbox::Pointer< VariableFillPattern< DIM > >	var_fill_pattern = `tbox::Pointer< BoxGeometryFillPattern< DIM > >()`
	)

Register a refine operation with the refine algorithm object. This routine supports time interpolation. Time interpolation will take place between the old and new source data components on coarser levels. On the destination level, data will be moved from the source component to the destination component using scratch component as a temporary work space. The scratch component must have sufficient ghost cells to cover the required operator stencil width and any needed physical boundary ghost cells. The time interpolation operator cannot be null. When assertion checking is active, passing in a null pointer will result in an unrecoverable exception.

Parameters

dst	Integer destination patch data index to be filled on the destination level.
src	Integer source patch data index on the source level.
src_told	Integer source patch data index for old data used in time interpolation.
src_tnew	Integer source patch data index for new data used in time interpolation.
scratch	Integer patch data index used as a temporary work space.
oprefine	tbox::Pointer to refinement operator. This may be a null pointer. In this case, refinement must be handled by the refine patch strategy member functions. See the comments for RefinePatchStrategy<DIM>::preprocessRefine() and RefinePatchStrategy<DIM>::postprocessRefine().
optime	tbox::Pointer to time interpolation operator. This pointer may not be null.

		tbox::Pointer< xfer::RefineTransactionFactory< DIM > >	transaction_factory = `(xfer::RefineTransactionFactory< DIM > *) NULL`
	)

Neither time nor spatial interpolation is performed.

Note that the schedule remains valid as long as the patches on the level do not change; thus, it can be used for multiple data communication cycles.

Returns: tbox::Pointer to refine schedule that performs the data transfers.

Parameters

level	tbox::Pointer to level on which interpatch transfers occur. This pointer cannot be null.
patch_strategy	Optional tbox::Pointer to a refine patch strategy that provides user-defined physical boundary filling operations. If this patch strategy is null (default state), then no physical boundary filling is performed.
transaction_factory	Optional tbox::Pointer to a refine transaction factory that creates data transactions for the schedule. If this pointer is null (default state), then a StandardRefineTransactionFactory object will be used.

		bool	use_time_interpolation = `false`,
		tbox::Pointer< xfer::RefineTransactionFactory< DIM > >	transaction_factory = `(xfer::RefineTransactionFactory< DIM > *) NULL`
	)

Note that both levels must reside in the same AMR hierarchy index space, or in index spaces that represent the same level of mesh refinement. No spatial interpolation is performed.

In certain rare cases it may be desired to use this schedule to perform time interpolation, in which case the use_time_interpolation optional argument should be set to true.

Note that the schedule remains valid as long as the patches on the levels do not change; thus, it can be used for multiple data communication cycles.

Returns: tbox::Pointer to refine schedule that performs the data transfers.

Parameters

dst_level	tbox::Pointer to destination level; cannot be null.
src_level	tbox::Pointer to source level; cannot be null.
patch_strategy	tbox::Pointer to a refine patch strategy that provides user-defined physical boundary filling operations. If this patch strategy is null (default state), then no physical boundary filling is performed.
use_time_interpolation	Optional boolean flag to create the schedule with the ability to perform time interpolation. Default is no time interpolation (false).
transaction_factory	Optional tbox::Pointer to a refine transaction factory that creates data transactions for the schedule. If this pointer is null (default state), then a StandardRefineTransactionFactory object will be used.

		bool	use_time_interpolation = `false`,
		tbox::Pointer< xfer::RefineTransactionFactory< DIM > >	transaction_factory = `(xfer::RefineTransactionFactory< DIM > *) NULL`
	)

In certain rare cases in may be necessary to perform time interpolation between old and new sources on the given patch level. In this case the optional argument use_time_interpolation should be set to true. Regardless of the value of this argument, time interpolation on coarser levels will always occur whenever needed.

Note that the next coarser level number must correspond to a level in the hierarchy that represents a region of coarser index space than the destination level.

Note that the schedule remains valid as long as the patches on the levels involved in its creation do not change; thus, it can be used for multiple data communication cycles.

Returns: tbox::Pointer to refine schedule that performs the data transfers.

Parameters

level	tbox::Pointer to destination level; cannot be null.
next_coarser_level	Integer number of next coarser patch level in the patch hierarchy relative to the destination level. Note that when the destination level has number zero (i.e., the coarsest level), this value should be < 0.
hierarchy	tbox::Pointer to patch hierarchy from which data to fill level should come. This pointer may be null only when the next_coarser_level is < 0.
patch_strategy	tbox::Pointer to a refine patch strategy that provides user-defined physical boundary filling operations and user-defined spatial interpolation operations. If this patch strategy is null (default state), then no physical boundary filling or user-defined interpolation is performed. Note that this may cause problems since interpolation of data from coarser levels to some finer level may require physical boundary data.
use_time_interpolation	Optional boolean flag to create the schedule with the ability to perform time interpolation Default is no time interpolation (false).
transaction_factory	Optional tbox::Pointer to a refine transaction factory that creates data transactions for the schedule. If this pointer is null (default state), then a StandardRefineTransactionFactory object will be used.

◆ createSchedule() [6/8]

template<int DIM>

tbox::Pointer< xfer::RefineSchedule<DIM> > SAMRAI::xfer::RefineAlgorithm< DIM >::createSchedule	(	tbox::Pointer< hier::PatchLevel< DIM > >	dst_level,
		tbox::Pointer< hier::PatchLevel< DIM > >	src_level,
		const int	next_coarser_level,
		tbox::Pointer< hier::PatchHierarchy< DIM > >	hierarchy,
		xfer::RefinePatchStrategy< DIM > *	patch_strategy = `((xfer::RefinePatchStrategy< DIM > *) NULL)`,
		bool	use_time_interpolation = `false`,
		tbox::Pointer< xfer::RefineTransactionFactory< DIM > >	transaction_factory = `(xfer::RefineTransactionFactory< DIM > *) NULL`
	)

This form of schedule construction is typically used after regridding (where the source level is the patch level being replaced by the destination level in the patch hierarchy) or when the data on destination patch level is to be overwritten by data interpolated from coarser levels in the patch hierarchy. In the first case, data on the destination level will be copied from the source level in regions where those two levels overlap and filled with interpolated values from the hierarchy elsewhere. In the latter case, the source level pointer may be null. Then, data on the destination level will be filled using interpolated data from coarser hierarchy levels.

In certain cases it may be necessary to perform time interpolation between old and new sources onto the destination level. In this case the optional argument use_time_interpolation should be set to true. Regardless of the value of this argument, time interpolation on coarser levels will always occur whenever needed.

Note that when the source level pointer is non-null, the index spaces of the source and destination levels must be aligned with one another.

Note that the schedule remains valid as long as the patches on the levels involved in its creation do not change; thus, it can be used for multiple data communication cycles.

Returns: tbox::Pointer to refine schedule that performs the data transfers.

Parameters

dst_level	tbox::Pointer to destination level; cannot be null.
src_level	tbox::Pointer to source level. This pointer may be null. In this case, data on the destination level will be filled only using interpolated data from coarser hierarchy levels. When this pointer is not null, the source level must live in the same AMR hierarchy index space as the destination level.
next_coarser_level	Integer number of next coarser patch level in a patch hierarchy relative to the destination level. Note that when the destination level has number zero (i.e., the coarsest level), this value should be < 0.
hierarchy	tbox::Pointer to patch hierarchy from which data to fill level should come. This pointer may be null only when the next_coarser_level is < 0.
patch_strategy	tbox::Pointer to a refine patch strategy that provides user-defined physical boundary filling operations and user-defined spatial interpolation operations. If this patch strategy is null (default state), then no physical boundary filling or user-defined interpolation is performed. Note that this may cause problems since interpolation of data from coarser levels to some finer level may require physical boundary data.
use_time_interpolation	Optional boolean flag to create the schedule with the ability to perform time interpolation Default is no time interpolation (false).
transaction_factory	Optional tbox::Pointer to a refine transaction factory that creates data transactions for the schedule. If this pointer is null (default state), then a StandardRefineTransactionFactory object will be used.
