§ MinUnbalDispNorm()

XC::MinUnbalDispNorm::MinUnbalDispNorm	(	AnalysisAggregation *	owr,
		double	lambda1,
		int	specNumIter,
		double	min,
		double	max,
		int	signFirstStep = `SIGN_LAST_STEP`

Constructor.

Parameters

owr	set of objects used to perform the analysis.

Member Function Documentation

§ domainChanged()

int XC::MinUnbalDispNorm::domainChanged ( void )

virtual

Make required changes when a change in the domain occurs.

Is called by the Analysis object. Refer to the Analysis classes to see when it is invoked. To return \(0\) if successful, a negative number if not. This base class returns \(0\).

Reimplemented from XC::Integrator.

§ recvSelf()

int XC::MinUnbalDispNorm::recvSelf ( const CommParameters & cp )

virtual

Receive the object.

Each object has to receive the data needed to be able to recreate itself in the new process after it has been sent through cp. If the object is an aggregation containing other objects, new objects of the correct type can be constructed using #theBroker. To return 0 if successful or a -1 if not.

Implements XC::MovableObject.

§ sendSelf()

int XC::MinUnbalDispNorm::sendSelf ( CommParameters & cp )

virtual

Send the object.

Each object has to send the data needed to be able to reproduce that object in a remote process. The object uses the methods provided by cp object to send the data to another channel at the remote actor, the address of the channel is set before this method is called. An object of similar type at the remote actor is invoked with a receiveSelf() to receive the data. Returns 0 if successful (successful in that the data got to the channel), or a - if no data was sent.

Implements XC::MovableObject.

§ update()

int XC::MinUnbalDispNorm::update ( const Vector & deltaU )

virtual

When invoked causes the integrator object to update the DOF_Group responses with the appropriate values based on the computed solution to the system of equations object.

Implements XC::IncrementalIntegrator.
