Detailed Description

A Node is like a Point, but with more information.

A Node is located in space and is associated with some (x,y,z) coordinates. Additionally, a Node may be enumerated with a global id. Finally, a Node may have an arbitrary number of degrees of freedom associated with it.

Author: Benjamin S. Kirk

Date: 2003 A geometric point in (x,y,z) space associated with a DOF.
