| 中文摘要: |
| 把表面细分技术应用于求解边界积分方程,既能把CAD模型直接用于边界元分析,又能精确描述复杂的边界几何形状,实现网格自动加密和形函数自动升阶,满足误差要求。把它应用于简单的二维声辐射和声散射,结果表明对提高边界元方法的计算精度是有效的。 |
| 英文摘要: |
| The subdivision surface technique, a new method in the Computer Graphics, has been paid more attention because of its exactness in depicting models. In this paper we apply the technique to the boundary element method and find that it can make the problem more easy to be computed, and the solution is more accurate. The new approach offers a method to use the CAD models straightforward to the boundary element method. |
