七十年代发展起来的边界单元法也叫做边界积分方程法,是一种数值方法。它只需对计算区的边界进行剖分,在求出边界上的未知量之后,对计算区内部任意点的物理量则只要根据边界上的已知量用简单的公式就可求出。
The boundary element method developed in the 1970s is also called boundary integral equation method and is a numerical method. It only needs to split the boundary of the calculation area. After finding the unknown quantity on the boundary, the physical quantity at any point within the calculation area can be obtained by a simple formula based on the known quantity on the boundary.
