三维精确局部加密网格划分在行波管模拟软件中的应用

摘要

通过半径与最小边之比控制网格质量,用三维分段线性结构(3D-PLC)作为网格初始数据进行自适应,用PLC进行局部加密形成Delaunay自适应网格划分方法,最后以螺旋线和电子枪为实例证明该方法的可行性.%Through radius to shortest edge ratio to control mesh quality, using 3D-PLC(piecewise linear complex) as mesh initial data to produce self-adaptive mesh, building a solution of delaunay self-adaptive mesh through 3D PLC local delaunay refinement. This method is validated by examples of helix and electron gun.
