Abstract:

Recent developments in software engineering and in the field of object-oriented C++ programming have made it possible to model physical processes and mechanism more expressively than ever before. And an interest in the use of object-oriented programming methods in finite element computing is growing. Specific ideas are provided for the development of object-oriented programming approach to the finite element analysis of multiphase seepage in an oil reservoir. The basic concepts of objects, classes, methods, and inheritance as well as an expandable application framework are introduced. According to the object-oriented programming methods and the equations of the finite element analysis of the multiphase flow in oil reservoir, the classes and their methods，which describe matrix，element，node, material, shape function etc., have been developed and implemented using the object-oriented programming language C++.NET. The program is implemented and a numerical example is simulated to show the programming of finite element method.

Key words: oil reservoir, multiphase seepage, object-oriented, finite element method, numerical simulation
