THE APPLICATION OF AXISYMMETRIC ELEMENT OF FINITE ELEMENT METHOD OF LINES IN THE ANALYSIS OF THERMAL FIELD

  • 摘要: 该文将有限元线法应用于温度场分析,提出了一种分析温度场的新方法。以轴对称单元为例,简要地阐述了有限元线法分析温度场的基本步骤。重点介绍了有限元线法分析在分析温度场中的理论推导过程,得出了常微分方程和对应的边界条件。选用高质量常微分方程组器求解所得的常微分方程组,通过调用子程序APPSLN可输出任一点的解答。

     

    Abstract: Finite Element Method Of Lines is used in the analysis of thermal field in this paper. Using axisymmetric element, the application of Finite Element Method Of Lines in the analysis of thermal field is illustrated. This paper presents the theoretical derivation for the application of Finite Element Method Of Lines, and obtains the ordinary differential equations and corresponding boundary conditions. High quality ordinary differential equations solver is selected to solve the ordinary differential equations. The temperature of an arbitrary point can be obtained by calling subroutine APPSLN.
