基于Java的OOFEM框架模型研究

Research on Java OOFEM Framework Model

面向对象的有限元(OOFEM)通用框架的构造对于有限元算法和并行有限元的研究具有重要意义。该文利用Java和面向对象技术,初步实现了这种非线性有限元框架模型,并且对其理论基础、功能构造、类库实现和算法设计等进行了研究。算例表明:数值结果与理论值是吻合的,框架模型是正确的和可靠的。

The construction of the general OOFEM framework model is very important for studying nonlinear FEM analysis algorithms and parallel FEM algorithms.By using Java and OO technology,the framework model is realized.The basic theories,function constitution,realization of class library,and design of algorithms are discussed.The computing sample shows that the numerical results are in good agreement with the theoretical solutions and the built framework is correct and reliable.
