Abstract

Abstract: As a numeric method，FEA mainly deals with the total stiffen matrix．In this paper，we can seethe progmm can run effectively with the mixead-Language program and the superiority of FORTRAN in numeric calculation．At last some typical numeric functions are given

Key words: numeric calculation, mixed-language program

摘要： 有限元作为一种数值计算方法，其核心在于对总刚度矩阵的各种处理．本文通过对其中数值方法的讨论，指出以混合编程的方式，利用FORTRAN上和数值计算资源及其在数值计算上的优势，能够很好的解决这个问题，提高程序的速度与效率．并给出了几个有代表性的函数的例子．

关键词: 有限元, 数值计算, 混合编程
