Documentation

StaticIntegrator is an abstract class. It is a subclass of IncrementalIntegrator provided to implement the common methods among integrator classes used in performing a static analysis on the FE_Model. The StaticIntegrator class provides an implementation of the methods to form the FE_Element and DOF_Group contributions to the tangent and residual. A pure virtual method newStep() is also defined in the interface, this is the method first called at each iteration in a static analysis, see the StaticAnalysis class.

StaticIntegrator(int classTag)

The integer classTag is passed to the IncrementalIntegrator classes constructor

virtual ~StaticIntegrator()

Does nothing. Provided so that the subclasses destructors will be called.

virtual int formEleTangent(FE_Element *theEle)

To form the tangent matrix of the FE_Element, theEle, is instructed to zero this matrix and then add it's K matrix to the tangent, i.e. it performs the following: \begin{tabbing} while \= \+ while \= while \= \kill theEle->zeroTang()

virtual int formEleResidual(FE_Element *theEle)

To form the residual vector of the FE_Element, theEle, is instructed to zero the vector and then add it's R vector to the residual, i.e. it performs the following: \begin{tabbing} while \= \+ while \= while \= \kill theEle->zeroResidual()

virtual int formNodTangent(DOF_Group *theDof)

This should never be called in a static analysis. An error message is printed if it is. Returns -1.

virtual int formNodUnbalance(DOF_Group *theDof)

To form the unbalance vector of the DOF_Group, theDof, is instructed to zero the vector and then add it's P vector to the unbalance, i.e. it performs the following: \begin{tabbing} while \= \+ while \= while \= \kill theDof->zeroUnbalance()
