Detailed Description

A TransformationDOF_Group object is instantiated by the TransformationConstraintHandler for every node in the domain which is constrained by an MFreedom_Constraint or an SFreedom_Constrant.

This object stores the transformation matrix \(T\) used by the TransformationFE objects

Member Function Documentation

§ getID()

const XC::ID & XC::TransformationDOF_Group::getID ( void ) const

virtual

Method to return the current ID.

A const member function which returns in an ID object the equation numbers associated with the degrees-of-freedom in the DOF_Group. The size of the ID object is equal to the number of degrees-of-freedom represented by the DOF_Group. This base class returns the ID created for the mapping.

Reimplemented from XC::DOF_Group.

§ getNumConstrainedDOF()

int XC::TransformationDOF_Group::getNumConstrainedDOF ( void ) const

virtual

Returns the total number of constrained DOFs.

Returns the total number of constrained DOFs in the DOF_Group, i.e. number of dof in the group who have been assigned a negative equation number. Determines this by looping through the ID containing the mapping information.

Reimplemented from XC::DOF_Group.

§ getNumFreeDOF()

int XC::TransformationDOF_Group::getNumFreeDOF ( void ) const

virtual

Returns the total number of free DOFs.

Returns the total number of free DOFs in the DOF_Group, i.e. number of dof in the group who have not been assigned a negative equation number. Determines this by looping through the ID containing the mapping information.

Reimplemented from XC::DOF_Group.

§ getTangent()

const XC::Matrix & XC::TransformationDOF_Group::getTangent ( Integrator * theIntegrator )

virtual

Returns the current tangent matrix for the DOF_Group.

Returns the current tangent matrix for the DOF_Group. If no tangent matrix has been created, one of size(numDOF,numDOF) is constructed. If not enough space is available for a new tangent matrix, an error message is printed and an error Matrix is returned..

Reimplemented from XC::DOF_Group.

§ incrNodeAccel()

void XC::TransformationDOF_Group::incrNodeAccel ( const Vector & udotdot )

virtual

Method to set the corresponding nodes accelerations increments to the values in u, components identified by myID.

Reimplemented from XC::DOF_Group.

§ incrNodeDisp()

void XC::TransformationDOF_Group::incrNodeDisp ( const Vector & u )

virtual

Method to set the corresponding nodes displacements increments to the values in u, components identified by myID.

Reimplemented from XC::DOF_Group.

§ incrNodeVel()

void XC::TransformationDOF_Group::incrNodeVel ( const Vector & u )

virtual

Method to set the corresponding nodes velocities increments to the values in u, components identified by myID.

Reimplemented from XC::DOF_Group.

§ setID()

void XC::TransformationDOF_Group::setID	(	int	index,
		int	value
	)

virtual

to set the corresponding index of the ID to value.

Operation to set the equation number of the {dof'th} DOF in the DOF_Group to value. In this base class, if index is a valid location, \(0 < index < numDOF-1\) the operator {(index) = value} is invoked on the ID object created for the mapping, otherwise an error message is printed.

Reimplemented from XC::DOF_Group.
