继有限单元法之后,近年来又出现了一种新的计算方法——边界单元法。该方法只要离散求解区域的边界,因而得到的离散代数方程组中的未知量也只是边界上的量。显然,它比用有限单元法求解时的未知量数目要少得多,输入数据和计算时间相应可以减 Following the finite element method, in recent years a new method of calculation has emerged - the Boundary Element Method. As long as the method discretely solves the boundary of the region, the unknown quantity in the system of discrete algebraic equations obtained is only the quantity on the boundary. Obviously, it is much less than the number of unknowns solved by the finite element method, and the input data and calculation time can be reduced accordingly
