摘要
三维边界单元法解空间弹性力学问题,只需将边界面划分为单元。本文对几何形状不规则或边界节点分布无规律的边界面,给出了将边界节点自动连结成三角形单元网格的一种方法。
Using BEM (Boundary Element Method) to solve three dimension elastic
problem, the boundary surface has to be dispersed into units. The article presents a
method to form triangulary boundary units automatically for the problems
with irregular curved surface and/or irregular joints
