Detailed Description

] at the locations corresponding to the constrained degree-of-freedom specified by the SFreedom_Constraint and the lagrange multiplier degree-of-freedom introduced by the LagrangeConstraintHandler for this constraint, where \(U_s\) is the specified value of the constraint and \(U_t\) the current trial displacement at the node corresponding to the constraint.

Member Function Documentation

§ getM_Force()

const XC::Vector & XC::LagrangeSFreedom_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::LagrangeSFreedom_FE::getResidual ( Integrator theNewIntegrator)
virtual

] where \(U_s\) is the specified value of the constraint and \(U_t\) the current trial displacement at the node corresponding to constrained degree-of-freedom.

Prints a warning message and sets this contribution to \(0\) if the specified constrained degree-of-freedom is invalid. Returns this residual Vector.

Reimplemented from XC::FE_Element.

§ getTangForce()

const XC::Vector & XC::LagrangeSFreedom_FE::getTangForce ( const Vector x,
double  fact = 1.0 
)
virtual

] where \(U_s\) is the specified value of the constraint and \(U_t\) the current trial displacement in disp corresponding to constrained degree-of-freedom.

Prints a warning message and sets this contribution to \(0\) if the specified constrained degree-of-freedom is invalid.

Reimplemented from XC::FE_Element.

§ setID()

int XC::LagrangeSFreedom_FE::setID ( void  )
virtual

Method to set the correSPonding index of the ID to value.

Causes the LagrangeSFreedom_FE to determine the mapping between it's equation numbers and the degrees-of-freedom. From the Node object link, created in the constructor, the DOF_group corresponding to the Node associated with the constraint is determined. From this {DOF_Group} object the mapping for the constrained degree of freedom is determined and the myID(0) in the base class is set. The myID(1) is determined from the Lagrange DOF_Group theGroup passed in the constructor. Returns \(0\) if successful. Prints a warning message and returns a negative number if an error occurs: \(-2\) if the Node has no associated DOF_Group, \(-3\) if the constrained DOF specified is invalid for this Node and \(-4\) if the ID in the DOF_Group is too small for the Node.

Reimplemented from XC::FE_Element.
