Member Function Documentation

§ getM_Force()

const XC::Vector & XC::PenaltyMRMFreedom_FE::getM_Force	(	const Vector &	disp,
		double	fact = `1.0`
	)

virtual

Returns the product of elements current mass matrix and a Vector whose values are obtained by taking the product of {fact} and those elements of the Vector accel associated with the FE_Elements equation numbers.

If no element is associated with the FE_Element or the associated element is a Subdomain a warning message is printed and an error Vector is returned.

Reimplemented from XC::FE_Element.

§ getResidual()

const XC::Vector & XC::PenaltyMRMFreedom_FE::getResidual ( Integrator * theNewIntegrator )

virtual

Computes and returns the residual vector.

Causes the FE_Element to determine it's contribution to the residual vector and to return this vector. If the Element is a Subdomain it invokes computeResidual()} and {getResistingForce() on the Subdomain. Otherwise {formEleResidual(this)} is invoked on theIntegrator and the resuting residual vector is returned. Subclasses must provide their own implementation. If no Element is passed in the constructor, a warning message and an error vector is returned.

Reimplemented from XC::FE_Element.

§ getTangent()

const XC::Matrix & XC::PenaltyMRMFreedom_FE::getTangent ( Integrator * theNewIntegrator )

virtual

Computes and returns the tangent stiffness matrix.

Causes the FE_Element to determine it's contribution to the tangent matrix and to return this matrix. If the Element is a Subdomain it invokes computeTangent()} and {getTang() on the Subdomain. Otherwise {formEleTangent(this)} is invoked on {theIntegrator} and the new tangent matrix is returned. Subclasses must provide their own implementation. If no Element is passed in the constructor, a warning message is printed and an error Matrix of size 1X1 is returned.

Reimplemented from XC::FE_Element.

§ getTangForce()

const XC::Vector & XC::PenaltyMRMFreedom_FE::getTangForce	(	const Vector &	disp,
		double	fact = `1.0`
	)

virtual

Returns the product of FE_Elements current tangent matrix and a Vector whose values are obtained by taking the product of {fact} and those elements of the Vector disp associated with the FE_Elements equation numbers.

If the element associated with the FE_Element is a subdomain, the tangent is obtained by invoking {getTang()} on the subdomain, otherwise the tangent is formed by invoking {formEleTang(this)} on the integrator object last used in a getTangent()} or {getResidual(). If no element is associated with the FE_Element a zero vector is returned and an error message is printed. An error message is also printed if invoking addMatrixVector() on the force vector returns \(< 0\).

Reimplemented from XC::FE_Element.
