Detailed Description
Nodes are points in space connected by the elements. Nodes have original position, trial displacement, velocity and acceleration, and committed displacement, velocity and acceleration (the last committed trial quantities). Nodes also store information about any load acting on the node, nodal mass and the nodal participation matrix. In addition, each Node object keeps track of it's associated DOF\_Group object. The Node interface provides methods to set and retrieve these quantities.\

constructors.
Definition at line 50 of file Node.cpp. |
|
Node::Node (
|
int tag,
|
|
int classTag )
|
|
|
|
To construct a node which has no data, other than the {classTag} identifier; 
and {classTag} are passed to the DomainComponent constructor. This is the constructor called by an FEM\_ObjectBroker. The data must be filled in subsequently by a call to {recvSelf()}.

|
Node::Node (
|
int tag,
|
|
int ndof,
|
|
double Crd1 )
|
|
|
|
To construct a node whose unique integer among nodes in the domain is given by {tag} and whose classTag is given by {classTag}. This constructor can be used by subclasses who wish to handle their own data management.
Definition at line 76 of file Node.cpp. |
|
Node::Node (
|
int tag,
|
|
int ndof,
|
|
double Crd1,
|
|
double Crd2 )
|
|
|
|
To construct a node for 1d problems whose unique integer among nodes in the domain is given by {tag} and whose original position in 1d space is given by (Crd1). With the node is associated {ndof} number of degrees of freedom. The class tag is NOD\_TAG\_Node (defined in classTags.h). A Vector object is created to hold the coordinates. No storage objects are created to hold the trial and committed response quantities, mass, load quantities; these are created as needed to reduce the memory demands on the system in certain situations.

To construct a node for 2d problems whose unique integer among nodes in the domain is given by {tag} and whose original position in 2d space is given by (Crd1,Crd2). With the node is associated {ndof} number of degrees of freedom. The class tag is NOD\_TAG\_Node. A Vector object is created to hold the coordinates.

|
|
|
|
To construct a node for 3d problems whose unique integer among nodes in the domain is given by {tag} and whose original position in 3d space is given by (Crd1,Crd2,Crd3). With the node is associated {ndof} number of degrees of freedom. The class tag is NOD\_TAG\_Node. A Vector object is created to hold the coordinates. No storage objects are created to hold the trial and committed response quantities, mass, load quantities; these are created as needed to reduce the memory demands on the system in certain situations.

This is a pure virtual method, one must be written for each instantiable subclass of MovableObject. Each object has to receive the data needed to be able to recreate itself in the new process after it has been sent through {theChannel}. If the object is an aggregation containing other objects, new objects of the correct type can be constructed using {theBroker}. To return
if successful or a 
if not.
Reimplemented from MovableObject.
