Some of the complications of automatic Delaunay mesh generation can be resolved using an edge based representation. In particular, difficult tasks such as maintaining object boundaries, region identification, and application specific issues such as rapid construction of stiffness matrices in finite element...
四.基于Delaunay三角剖分的网格生成算法 三角网格生成(mesh generation)算法有很多种,这里我们介绍基于Delaunay三角剖分的算法(其他还有波前法,八叉树方法等等)。 图6.左图的几何模型由点、线、面等几何元素组成,右图为基于Delaunay三角剖分生成三角网格,全部由三角形组成。 在实际应用中,三角网格生成的对象大多是三维...

好的三角剖分一般满足下面4个要求(摘自Delaunay Mesh Generation) First, large angles (near 180◦ ) can cause large interpolation errors. In the finite element method, these errors induce a large discretization error—the difference between the computed approximation and the true solution of the PDE...
Linux系统常用的网络操作命令包括 netstat nslookup host finger和 ping netstat 命令的功能是显示网络连接 路由表和网络接口信息,可以让用户得知 目前都有哪些网络连接正在运作 nslookup 命令的功能是查询一台机器的 IP 地址和其对应的域名 它通常需要一台域名服务器来提供域名服务 如果用 户已经设置好域名服务器 就...
Linux系统中最常用的网络配置命令包括 ifconfig route 其中 ifconfig 用来查 看和配置网络接口 通常是网卡 信息 包括网络接口设备的 IP 地址 掩码 等route 用来管理 Linux系统内核中的路由表 它最大的用途就是用来设定 静态的路由表项 通常是在系统用 ifconfig 配置网络接口后 用它来设定主机 或者一网段的 IP 地...
