| 摘 要： | 基于Thompson曲线网格生成方法,导出一组新的调节函数P、Q的表达式,并给出了曲线网格生成实例。实例检验表明,该调节函数能够对复杂边界的单连通域或多连通域生成理想的曲线网格,即网格近似正交,网格分布能够适应物理量场变化的情形。在实际水利工程流场数值模拟中,该方法能够准确地使用边界条件,提高求解精确度。

| Abstract: | Based on the Thompson method for grid generation,the expression for a new group of adjusting functions as a P and Q was derived.The curvilinear grid generation example showed that this adjusting function can form the ideal curve grid for simple connected regions and multi-connected regions with complied boundary.The curvilinear grid are orthogonal and the grids distribution adapt to the variation of physical parameters.The proposed method can accurately use the boundary conditions and improve the computation accuracy in numerical simulation of water velocity field. |
