Detailed Description

Base class for DOF numbererers.

DOF numberers purpose is to define the interface common among all subclasses. A DOF_Numberer object is responsible for assigning the equation numbers to the individual dofs in each of the DOF_Groups in the AnalysisModel. The base DOF_Numberer uses a GraphNumberer object to first number the DOF_Groups, based on the ordering of the DOF_Group objects, it assigns the equation numbers to the individual degrees-of-freedom. Subtypes may wish to implement the numbering in a more efficient manner by using the FE_Element and DOF_Group objects directly.

Member Function Documentation

§ getGraphNumbererPtr() [1/2]

XC::GraphNumberer * XC::DOF_Numberer::getGraphNumbererPtr ( void  )
protected

Return a pointer to the GraphNumberer object associated with the DOF_Numberer, theGraphNumberer.

§ getGraphNumbererPtr() [2/2]

const XC::GraphNumberer * XC::DOF_Numberer::getGraphNumbererPtr ( void  ) const
protected

Return a const pointer to the GraphNumberer object associated with the DOF_Numberer, theGraphNumberer.

§ numberDOF() [1/2]

int XC::DOF_Numberer::numberDOF ( int  lastDOF_Group = -1)
virtual

Invoked to assign the equation numbers to the dofs.

Invoked to assign the equation numbers to the dofs in the DOF_Groups and the FE_Elements, ensuring that the dof's in the DOF_Group whose tag is given by {lastDOF_Group} are numbered last in a \(-2\) or \(-3\) group. The initial values of these equation numbers have been set by the ConstraintHandler object to be \(-1\), \(-2\) or \(-3\), all dofs with a \(-3\) are to be assigned higher equation numbers than those assigned a \(-2\). To set the numEqn in the AnalysisModel and to return the number of equations numEqn if successful, a negative number if not. This base class performs the ordering by getting an ID containing the ordered DOF_Group tags, obtained by invoking {number(theModel- \(>\)getDOFGroupGraph(), lastDOF_Group)} on the GraphNumberer, theGraphNumberer, passed in the constructor. The base class then makes two passes through the DOF_Group objects in the AnalysisModel by looping through this ID; in the first pass assigning the equation numbers incrementally to any degree-of-freedom marked with a \(-2\) and in the second pass assigning the equation numbers incrementally to any degree-of-freedom marked with a \(-3\). It then iterates through the FE_Elements in the AnalsisModel invoking {setID()} on each object. Finally {setNumEqn(numEqn)} is invoked on the AnalysisModel. Return numEqn if successful, a warning message and a negative number is returned if an error occurs; \(-1\) is returned if setLinks() has not yet been invoked, \(-2\) if no GraphNumberer was passed in the constructor, \(-3\) if the number of {DOF_Groups} in AnalysisModel and size of ID returned are not the same, and a \(-4\) if there is no DOF_Group corresponding to one of the tags given in the ID.

Reimplemented in XC::ParallelNumberer, and XC::PlainNumberer.

§ numberDOF() [2/2]

int XC::DOF_Numberer::numberDOF ( ID lastDOFs)
virtual

Invoked to assign the equation numbers to the dofs.

Invoked to assign the equation numbers to the dofs in the DOF_Groups and the FE_Elements, ensuring that the dof's in the DOF_Groups whose tag is given in {lastDOF_Groups} are numbered last in a \(-2\) or \(-3\) group. The initial values of these equation numbers have been set by the ConstraintHandler object to be \(-1\), \(-2\) or \(-3\), all dofs with a \(-3\) are to be assigned higher equation numbers than those assigned a \(-2\). To set the numEqn in the AnalysisModel and to return the number of equations numEqn if successful, a negative number if not.

This method in the base class is almost identical to the one just described. The only difference is that the ID identifying the order of the DOF_Groups is obtained by invoking {number(theModel- \(>\)getDOFGroupGraph(), lastDOF_Groups)} on the GraphNumberer.

Reimplemented in XC::ParallelNumberer, and XC::PlainNumberer.

§ recvData()

int XC::DOF_Numberer::recvData ( const CommParameters cp)
protected

Receives object members through the channel being passed as parameter.

The DOF_Numberer receives the class identifier and database tag of the GraphNumberer in an ID from the channel, if no GraphNumberer is associated a \(-1\) is received. The DOF_Numberer will then ask {theBroker} for a GraphNumberer with that class identifier, it sets the database tag for the GraphNumberer and it then invokes {recvSelf()} on that GraphNumberer.

§ sendData()

int XC::DOF_Numberer::sendData ( CommParameters cp)
protected

Send object members through the channel passed as parameter.

The DOF_Numberer sends the class identifier and database tag of the GraphNumberer in a ID to the channel, if no GraphNumberer is associated a \(-1\) is sent as the class tag. The object then invokes sendSelf() on the GraphNumberer.

§ useAlgorithm()

void XC::DOF_Numberer::useAlgorithm ( const std::string &  nmb)

Sets the algorithm to be used for numerating the graph «Reverse Cuthill-Macgee» o simple.
