Detailed Description

{staticFormTaylor} {equation}

which a system of of \(N\) equations with ( \(N+1\)) unknowns. Two solve this, an additional equation is required, the constraint equation. The constraint equation used depends on the static integration scheme, of which there are a number, for example load control, arc length, and displacement control.

Member Function Documentation

§ formEleResidual()

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

virtual

To form the residual vector of the FE_Element.

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: {tabbing} while \= + while \= while \= theEle- \(>\)zeroResidual() theEle- \(>\)addRtoResid() {tabbing} The method returns \(0\).

Implements XC::IncrementalIntegrator.

Reimplemented in XC::StaticSensitivityIntegrator.

§ formEleTangent()

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

virtual

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

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: {tabbing} while \= + while \= while \= theEle- \(>\)zeroTang() theEle- \(>\)addKtoTang() {tabbing} The method returns \(0\).

Implements XC::IncrementalIntegrator.

§ formNodTangent()

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

virtual

This should never be called in a static analysis.

An error message is printed if it is. Returns -1.

Implements XC::IncrementalIntegrator.

§ formNodUnbalance()

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

virtual

Form the unbalance vector for the DOF_Group.

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: {tabbing} while \= + while \= while \= theDof- \(>\)zeroUnbalance() theDof- \(>\)addPtoUnbal() {tabbing} The method returns \(0\).

Implements XC::IncrementalIntegrator.
