Transfinite Interpolation Grid Generation with the Application of B Spline
【摘要】 采用B样条曲线曲面生成技术与传统网格生成方法中超限插值技术 ,并将两者结合起 ,形成一种计算网格的生成方法 .它发挥了两者的优点和长处 :能充分反映复杂外形的完全信息 ,提高对外形的适应程度 ;可控制切矢的边界条件 ,提高生成网格的质量 .算例表明了上述特点 .
【Abstract】 A grid generation method by applying B spline curve lines and surfaces to transfinite interpolation approaches is suggested. Numerical results demonstrate that detailed information about geometry shape can be included and so the method can be used to different complex geometries. Discussions are also made about how to adjust the boundary tangential vectors and the inner point array which forms a skeleton of the final grids. The results show that this method can generate high quality grids.
