Isoparametric element algorithm framework design based on Jaumin

SUN Yunjian;SUN Le;Institute of System Engineering,China Academy of Engineering Physics;  
As to the calculation characteristics of isoparametric finite elements and the development requirements of various kinds of elements in finite element software,based on the high performance computing program development framework Jaumin,an algorithm framework of isoparametric element is designed for the finite element software PANDA by abstraction and polymorphism technique and factory pattern using object-oriented language. The framework has good reusability and scalability,of which the development process is clear and can help to improve development efficiency. The corresponding classes and class interfaces of each module in the framework of isoparametric element algorithm are given. The examples show that the calculation results obtained by the isoparmetric element in PANDA is consistent with the results obtained by ANSYS.
