【摘要】 针对铺路法的不足,提出了一种基于分层发散思想的有限元网格生成方法。详细介绍了这种分层发散网格生成过程中的初始条件确定、布点、布点加速方法等网格划分处理的关键内容,在分层发散法产生的节点基础上进行网格生成。通过大量的网格生成实例验证了本算法对2-D区域进行网格划分的可行性。更多还原

【Abstract】 Paving method has received wide acceptance, which generates all-quadrilateral meshes in an arbitrary 2-D region. However, it has several defects, such as the complexity of making program and irregular mesh. In order to avoid those defects of the paving, a new algorithm, named delamination and divergence algorithm, has been put forward. The process of points distributing and mesh generating was described in detail. Methods to speed up the mesh procedure were discussed. Experimental results showed that the delamination and divergence method is effective and efficient.更多还原
