Degree of freedom management method for finite-element (FE) calculation of structures, requires selecting part-geometries from design model in order to simplify the kinematic description of the design model

摘要

Associated base masks initially selected for mathematically describing defined selected kinematic properties and then the part-geometries selected (20) to form the design model, followed by accumulating (30) selected kinematic features into system nodes. Combination masks are formed (50) by multiplication of base masks' components. Finally degree of freedom control-lists system are formed (70).
