00032 // Description: This file contains the class definition for
00033 // TransformationConstraintHandler. TransformationConstraintHandler is a
00034 // constraint handler for handling constraints using the Transformation method.
00035 // for each element and degree-of-freedom at a node it constructs regular
00036 // FE_Element and DOF_Groups if there is no SP_Constraint or MP_Constraint
00037 // constraining an elements node or the node; otherwise a TransformationFE
00038 // element and a TransformationDOF_Group are created.
