Detailed Description

Class implementing slave node connected to other nodes (masters) using predetermined weights.

Hanging node possess no degrees of freedom - all values are interpolated from corresponding master dofs.

The contributions of hanging node are localized directly to master related equations. The node can not have its own boundary or initial conditions, they are determined completely from master dof conditions except for dofs of master type.

Constructor & Destructor Documentation

oofem::SlaveNode::SlaveNode	(	int	n,
		Domain *	aDomain
	)

inline

Constructor.

Creates a hanging node with number n, belonging to aDomain.

Parameters

n	Node number in domain aDomain.
aDomain	Domain to which node belongs.

virtual oofem::SlaveNode::~SlaveNode ( void )

inlinevirtual

Destructor.

Member Function Documentation

virtual const char* oofem::SlaveNode::giveClassName ( ) const

inlinevirtual

Returns: Class name of the receiver.

Reimplemented from oofem::Node.

Definition at line 80 of file slavenode.h.

virtual const char* oofem::SlaveNode::giveInputRecordName ( ) const

inlinevirtual

Returns: Input record name of the receiver.

Reimplemented from oofem::Node.

Definition at line 81 of file slavenode.h.

References _IFT_SlaveNode_Name.

IRResultType oofem::SlaveNode::initializeFrom ( InputRecord * ir )

virtual

Initializes receiver according to object description stored in input record.

This function is called immediately after creating object using constructor. Input record can be imagined as data record in component database belonging to receiver. Receiver may use value-name extracting functions to extract particular field from record.

See also: IR_GIVE_FIELD; IR_GIVE_OPTIONAL_FIELD

Parameters

ir	Input record to initialize from.

Returns: IRResultType

Todo:: This is unnecessary, we should just check if user has supplied a dofidmask field or not and just drop "numberOfDofs"). It is left for now because it will give lots of warnings otherwise, but it is effectively ignored.

Todo:: This should eventually be removed, still here to preserve backwards compatibility:

virtual bool oofem::SlaveNode::isDofTypeCompatible ( dofType type ) const

inlinevirtual

Returns true if dof of given type is allowed to be associated to receiver.

Reimplemented from oofem::Node.

Definition at line 77 of file slavenode.h.

void oofem::SlaveNode::postInitialize ( )

virtual

Performs post-initialization such like checking if there are any slave dofs etc.

Reimplemented from oofem::DofManager.

Definition at line 63 of file slavenode.C.

References oofem::FloatArray::clear(), oofem::SlaveDof::initialize(), masterDofManagers, masterWeights, and oofem::DofManager::postInitialize().

void oofem::SlaveNode::updateLocalNumbering ( EntityRenumberingFunctor & f )

virtual

Local renumbering support.

For some tasks (parallel load balancing, for example) it is necessary to renumber the entities. The various FEM components (such as nodes or elements) typically contain links to other entities in terms of their local numbers, etc. This service allows to update these relations to reflect updated numbering. The renumbering function is passed, which is supposed to return an updated number of specified entity type based on old number.
