Detailed Description

Base class for the objects that performs the integration of physical properties over the domain to form the system stiffness matrix.

The Integrator class is an abstract base class. Its purpose is to define the interface common among all subclasses. An integrator method is responsible for defining how the system of equations are set up (this it does by specifying how the FE_Element and DOF_Group objects of the analysis model construct the vectors and matrices asked of them by the Analysis). It is also responsible for updating the response quantities at the DOFs with the appropriate values; the values are determined from the solution to the system of equations.

Member Function Documentation

§ domainChanged()

int XC::Integrator::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 in XC::DisplacementControl, XC::MinUnbalDispNorm, XC::DistributedDisplacementControl, and XC::ProtoArcLength.

§ formEleResidual()

virtual int XC::Integrator::formEleResidual ( FE_Element * theEle )

pure virtual

Called upon to determine the FE_Element theEles vector contribution to the SystemOfEqn object.

To return \(0\) if successful, a negative number otherwise.

Implemented in XC::StaticIntegrator, XC::IncrementalIntegrator, XC::EigenIntegrator, and XC::StaticSensitivityIntegrator.

§ formEleTangent()

virtual int XC::Integrator::formEleTangent ( FE_Element * theEle )

pure virtual

Called upon to determine the FE_Element theEles matrix contribution to the SystemOfEqn object.

To return \(0\) if successful, a negative number otherwise.

Implemented in XC::StaticIntegrator, XC::IncrementalIntegrator, and XC::EigenIntegrator.

§ formNodTangent()

virtual int XC::Integrator::formNodTangent ( DOF_Group * theDof )

pure virtual

Called upon to determine the DOF_Group theDofs matrix contribution to the SystemOfEqn object.

To return \(0\) if successful, a negative number otherwise.

Implemented in XC::StaticIntegrator, XC::IncrementalIntegrator, and XC::EigenIntegrator.

§ formNodUnbalance()

virtual int XC::Integrator::formNodUnbalance ( DOF_Group * theDof )

pure virtual

To return \(0\) if successful, a negative number otherwise.

Implemented in XC::StaticIntegrator, XC::IncrementalIntegrator, and XC::EigenIntegrator.

§ getAnalysisModelPtr() [1/2]

XC::AnalysisModel * XC::Integrator::getAnalysisModelPtr ( void )

protectedvirtual

Returns a pointer to the analysis model.

A member function which returns a pointer to the AnalysisModel associated with the Integrator object, i.e. theModel.

§ getAnalysisModelPtr() [2/2]

const XC::AnalysisModel * XC::Integrator::getAnalysisModelPtr ( void ) const

protectedvirtual

Returns a pointer to the analysis model.

A const member function which returns a const pointer to the AnalysisModel associated with the Integrator object, i.e. theModel.

§ getLastResponse()

virtual int XC::Integrator::getLastResponse	(	Vector &	result,
		const ID &	id
	)

pure virtual

Called upon to get the result quantities for the components specified in the ID id and to place them in the Vector result.

This is provided for domain decomposition methods. To return \(0\) if successful, a negative number otherwise.

Implemented in XC::IncrementalIntegrator, and XC::EigenIntegrator.

§ Print()

void XC::Integrator::Print	(	std::ostream &	os,
		int	flag = `0`
