int FEData::loadComplete ( )

inlinevirtual

Function called to signal to the FiniteElementData implementation that data-loading is complete and any synchronization or other final operations may be performed now. This is a collective function, must be called by all processors.

Returns: error-code 0 if successful

Implements FiniteElementData.

Definition at line 258 of file FEData.hpp.

int FEData::launchSolver	(	int &	solveStatus,
		int &	iterations
	)

inlinevirtual

Function called to request the launching of the linear solver.

Parameters

solveStatus	Output, should indicate the status of the solve. A successful solve is usually indicated by a value of 0.
iterations	Output, how many iterations were performed.

Returns: error-code, 0 if convergence tolerance was achieved within the specified maximum number of iterations. If error return is non-zero, the calling application will be expected to check solveStatus, and consult the solver-library's documentation to figure out exactly what happened.

Implements FiniteElementData.

Definition at line 274 of file FEData.hpp.

int FEData::reset ( )

inlinevirtual

Function to signal that all coefficient values should be zero'd in preparation for a new assemble/solve phase. This is to handle cases where no structural information is changing from one time-step to the next, but new coefficient values need to be loaded for the next solve.

Implements FiniteElementData.

Definition at line 284 of file FEData.hpp.

int FEData::deleteConstraints ( )

inlinevirtual

Function to signal that lagrange multiplier constraints should be deleted.

Implements FiniteElementData.

		int	fieldSize,
		int	numNodes,
		const int *	nodeNumbers,

	)

inlinevirtual

Pass nodal data that probably doesn't mean anything to the FEI implementation, but may mean something to the linear solver. Examples: geometric coordinates, nullspace data, etc.

Parameters

fieldID	Identifier for the field that describes this data. Lists of field identifiers and field sizes defined for the finite-element problem may be obtained from the Lookup interface that is supplied to the ESI_Broker by the FEI implementation.
nodeNumbers	List of nodes for which data is being supplied.

data	List of length numNodes * (size of field 'fieldID')

Implements FiniteElementData.
