A new object-oriented finite element analysis program architecture

摘要

This paper presents a new architecture for finite element analysis software, developed using object-oriented design. The resulting system is capable of the modeling and simulation of structural behavior, including the consideration of nonlinear static and dynamic effects. An innovation of the system design is the creation of several classes of objects that separate the analysis tasks from the details of the finite element model. This separation leads to flexible, extensible code. The overall system design and a prototype implementation are presented.
