Detailed Description

Class implementing hanging node connected to other nodes (masters) using interpolation.

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

The introduction of hanging nodes allows, for example, to include reinforcing bar elements inside arbitrary FE-mesh of concrete specimen or facilitates the local refinement of FE-mesh.

The contributions of hanging node are localized directly to master related equations. The hanging node can not have its own boundary or initial conditions, they are determined completely from master dof conditions. The local coordinate system in slave is not supported in current implementation, the global cs applies. On the other hand, hanging node can be loaded independently of master.

If no master element number is supplied (or negative) then it will locate it using the global coordinates. and if no master region number is supplied (or zero), it will look for elements in all regions.

Member Function Documentation

int oofem::qcNode::checkConsistency ( )

virtual

Allows programmer to test some internal data, before computation begins.

For example, one may use this function, to ensure that element has material with required capabilities is assigned to element. This must be done after all mesh components are instanciated.

Returns: Nonzero if receiver is consistent.

IRResultType oofem::qcNode::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.
