Documentation

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.

Node(int classTag)

To construct a node which has no data, other than the classTag identifier; 0 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(int tag, int classTag)

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.
