overridevirtualinherited

Reimplemented from IBTK::GeneralSolver.

◆ setSolutionTime()

void IBTK::FACPreconditioner::setSolutionTime ( double solution_time )

overridevirtualinherited

Reimplemented from IBTK::GeneralSolver.

◆ setTimeInterval()

	)

overridevirtualinherited

Reimplemented from IBTK::GeneralSolver.

◆ solveSystem()

bool IBTK::FACPreconditioner::solveSystem	(	SAMRAI::solv::SAMRAIVectorReal< NDIM, double > &	x,
		SAMRAI::solv::SAMRAIVectorReal< NDIM, double > &	b
	)

overridevirtualinherited

Before calling solveSystem(), the form of the solution x and right-hand-side b vectors must 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 solution and right-hand-side vectors. In particular, patch data in these vectors must be allocated prior to calling this method.

Parameters

x	solution vector
b	right-hand-side vector

Conditions on Parameters:

vectors x and b must have same patch hierarchy
vectors x and b must have same structure, depth, etc.

Note: The vector arguments for solveSystem() need not match those for initializeSolverState(). However, there must be a certain degree of similarity, including:

hierarchy configuration (hierarchy pointer and range of levels)
number, type and alignment of vector component data
ghost cell widths of data in the solution x and right-hand-side b vectors

Note: The solver need not be initialized prior to calling solveSystem(); however, see initializeSolverState() and deallocateSolverState() for opportunities to save overhead when performing multiple consecutive solves.

See also: initializeSolverState; deallocateSolverState

Returns: true if the solver converged to the specified tolerances, false otherwise

Implements IBTK::GeneralSolver.

◆ initializeSolverState()

void IBTK::FACPreconditioner::initializeSolverState	(	const SAMRAI::solv::SAMRAIVectorReal< NDIM, double > &	x,
		const SAMRAI::solv::SAMRAIVectorReal< NDIM, double > &	b
	)

overridevirtualinherited

By default, the solveSystem() method computes some required hierarchy dependent data before solving and removes that data after the solve. For multiple solves that use the same hierarchy configuration, it is more efficient to:

initialize the hierarchy-dependent data required by the solver via initializeSolverState(),
solve the system one or more times via solveSystem(), and
remove the hierarchy-dependent data via deallocateSolverState().

Note that it is generally necessary to reinitialize the solver state when the hierarchy configuration changes.

When linear operator or preconditioner objects have been registered with this class via setOperator() and setPreconditioner(), they are also initialized by this member function.

Parameters

x	solution vector
b	right-hand-side vector

Conditions on Parameters:

vectors x and b must have same patch hierarchy
vectors x and b must have same structure, depth, etc.

Note: The vector arguments for solveSystem() need not match those for initializeSolverState(). However, there must be a certain degree of similarity, including:

hierarchy configuration (hierarchy pointer and range of levels)
number, type and alignment of vector component data
ghost cell widths of data in the solution x and right-hand-side b vectors

Note: It is safe to call initializeSolverState() when the state is already initialized. In this case, the solver state is first deallocated and then reinitialized.

See also: deallocateSolverState

Reimplemented from IBTK::GeneralSolver.

◆ deallocateSolverState()

void IBTK::FACPreconditioner::deallocateSolverState ( )

overridevirtualinherited

When linear operator or preconditioner objects have been registered with this class via setOperator() and setPreconditioner(), they are also deallocated by this member function.

Note: It is safe to call deallocateSolverState() when the solver state is already deallocated.
