curvilinear grid meaning in English
曲线网格
Examples
- Numerical methods currently used cannot fit the complex geometry well because of the utility of rectangle and orthogonal curvilinear grids
但是，数值模型多采用矩形网格和正交曲线网格，对自然界复杂的几何边界适应能力较弱。 - Based on poission equation conversion , generated methods of curvilinear grids are presented . 4 . 2 - d flow and sediment transport model with non - staggered curvilinear grids is presented
( 3 )以poission方程变换为基础，建立拟合曲线坐标系下非正交和正交曲线网格生成方法。 - The total pressure is subdivided into the hydrostatic and residual hydrodynamic components . k - e turbulent flows model , non - staggered curvilinear grids , momentum interpolation , simplec and simpler algorithms are used to solve the basic equations
水流运动方程压力项分解为静水压力和动水压力，紊动粘性系数由k紊流模型求解，非交错网格减化方程离散，降低插值运算。 - Second , a parallel adaptive ray - casting algorithm for graphic rendering of cfi is developed . in the computational model of cfi , the line - of - sight integration is difficult to obtain for 3d complicated flow field , because curvilinear grids , multizone curvilinear grids , and other irregular grids that are commonly used in computational fluid dynamics ( cfd ) present interesting challenges , such as the complex shapes of cell regions defined by grid points ; the wide variation in the sizes of cells in different regions of the grid ; and the intersecting or overlapping nature of multi - grids . the parallel adaptive ray - casting algorithm is extremely efficient to solve these problems
并行自适应光线投射法继承了光线投射法适合于任何形式网格的优点；光线与计算网格的交点自适应地反映了原来网格点物理量的分布，能够与数值计算的精度保持一致；图像平面的自适应算法使我们不必从每一个像素发出射线，既提高了光线投射法的计算效率，同时又保证重采样后激波这样的高频信息不会损失；将并行处理技术引入计算光学流动图像生成过程，解决了大规模数值模拟结果的处理对计算速度和内存容量的需求。 - On base of the data analysis , three - dimensional tide - induced residual currents , the wind - driven and thermohaline currents in the bohai sea are diagnostically computed with an orthogonal curvilinear grid system , by means of a three - dimensional ecomsed model . the winter and summer thermohaline structure and circulation characteristics in bohai sea are analysed , and the circulation variance is discussed preliminarily . the tides and tidal currents in bohai sea are well reproduced
