Member Function Documentation

§ formEleResidual()

int XC::EigenIntegrator::formEleResidual ( FE_Element * theEle )

virtual

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

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

Implements XC::Integrator.

§ formEleTangent()

int XC::EigenIntegrator::formEleTangent ( FE_Element * theEle )

virtual

Asks the element being passed as parameter to build its mass(flagK= false) or stiffness matrix (flagK= true).

Implements XC::Integrator.

§ formEleTangK()

int XC::EigenIntegrator::formEleTangK ( FE_Element * theEle )

virtual

Asks the element being passed as parameter to build its tangent stiffness matrix.

§ formEleTangM()

int XC::EigenIntegrator::formEleTangM ( FE_Element * theEle )

virtual

Asks the element being passed as parameter to build its mass matrix.

Reimplemented in XC::KEigenIntegrator.

§ formNodTangent()

int XC::EigenIntegrator::formNodTangent ( DOF_Group * theDof )

virtual

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

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

Implements XC::Integrator.

§ formNodUnbalance()

int XC::EigenIntegrator::formNodUnbalance ( DOF_Group * theDof )

virtual

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

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

Implements XC::Integrator.

§ getLastResponse()

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

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.

Implements XC::Integrator.

§ recvSelf()

int XC::EigenIntegrator::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::EigenIntegrator::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.
