一、前言 本文给出一种求解任意几何形状、边界条件随时间无规则变化时的不稳定导热问题的方法。当只需要求解由系统的动态温度分布所构成的有限几个参数长期随时间的变化、并不要求温度场本身时,这种方法比通常的有限元法节省大量计算机时间,并获得更高精度。本文还给出便于实际应用的几种算法模式和一些具体处理措施。 I. Preface This paper presents a method for solving the problem of unstable thermal conductivity with arbitrary geometric shapes and boundary conditions changing randomly over time. This method saves a lot of computer time and gives more precision than the usual finite element method when it is only necessary to solve the long-term change with time of a limited number of parameters composed of the dynamic temperature distribution of the system and does not require the temperature field itself . This article also gives several practical application of the algorithm model and some specific measures.
