提出了一种基于前沿推进法的平面区域三角化网格剖分方法 ,它具有算法简单、易于编程和浮点计算量少的特点 ,同时可以克服以往算法在角点处可能出现一个单元的3个节点全在边界上的缺点。剖分实例表明 :该方法的鲁棒性和普适性较好 ,剖分结果经过光滑后 ,可用于多连通域中传热和流动问题的控制容积积分法的求解。 This paper presents a planar area triangulation meshing method based on frontal propulsion method. It has the characteristics of simple algorithm, easy programming and less floating point calculation. At the same time, All nodes on the border of the shortcomings. The example shows that this method is robust and universally applicable. After the smoothing of the results, the proposed method can be used to solve the problem of heat transfer and flow in a multi-connected domain by the integrated volume control method.
