Detailed Description

Interface to provide access to structural element nodes.

Each node is associated with six degrees of freedom, comprised of three translational components and three rotational components. Each node has its own orthogonal coordinate system. The node-local system provides the directions in which the equations of motion for the node are solved, and also defines the direction in which the node can be attached to a target entity via a link.
