XC::DOF_Group Class Reference

A DOF_Group object is instantiated by the ConstraintHandler for every unconstrained node in the domain. The constrained nodes require specialised types of DOF_Group; which deal with the constraints. DOF_Group objects can handle 0 boundary constraints; if the eqn number of a DOF is less than START_EQN_NUM a value of 0.0 is set for disp, vel and accel when a setNode*(Vector &) is invoked. More...

Detailed Description

A DOF_Group object is instantiated by the ConstraintHandler for every unconstrained node in the domain. The constrained nodes require specialised types of DOF_Group; which deal with the constraints. DOF_Group objects can handle 0 boundary constraints; if the eqn number of a DOF is less than START_EQN_NUM a value of 0.0 is set for disp, vel and accel when a setNode*(Vector &) is invoked.
