摘要
文章针对复杂曲面主要是裁剪曲面提出了一种便捷的网格生成方法.首先对曲面进行几何分块,把曲面分解成相连多个凸区域,然后对每个凸区域利用铺砌法生成四边形网格,最后对区域边界进行调节,从而生成整个曲面的网格.这种方法避免了复杂曲面特别是裁剪曲面直接网格生成时内部网格的扭曲、畸变.
The paper discusses a convenient and prompt method of creating grids for the complex curved surface, especially the cutting surface. First, it carries on the geometry piecemeal to the curved surface and decomposes the curved surface into many connected raised regions. Then the method of spreading is used to make each raised regions into the quadrangle grid. Last, the boundary of the region is adjusted, thus forming the entire grid of the curved surface. This method can avoid the distortion of the complex curved surface, especially the cutting surface when the direct grid is changed into the internal grid.
