Detailed Description

DOF\_Group is a base class. An object of type DOF\_Group represents an unconstrained node of the domain in the model. Each node in the domain is associated with one DOF\_Group. DOF\_Groups are called upon in the analysis to provide their contributions of unbalanced load to the system of equations. Subclasses are used by the constraint handler to to introduce new dofs into the analysis.

The DOF\_Group is responsible for providing operations to set and access the mapping betwwen equation numbers and DOFs, allowing the Integrator to from the tangent (if nodal masses in transient problem) and unbalanced load information, and for setting and obtaining the nodal trial response quantities. \
