查询词典 rectangular coordinates

Dendrite growth has been simulated with the phase field method and finite difference schemes on a two dimensional rectangular domain with a uniform square mesh.

采用相场模型和有限差分方法，模拟了过冷纯金属熔体的枝晶生长，计算区域为二维正方形均匀网格。

To improve the simulation accuracy and to make the increment of computation amount the smallest, the quantitative comparison was used to compare the effect of incident direction and difference accuracy on numerical dispersion with the changing of the ratio of horizontal and vertical gird. The results show that the rectangular grid is better than square mesh in suppressing dispersion and can avoid the low computational efficiency caused by high-order difference.

为提高模拟精度，同时又尽可能减少计算量，采用定量分析的方法，对比分析了横纵网格比变化时入射方向和差分精度等因素对数值频散的影响，分析结果表明，矩形网格较之正方形网格能更好地压制频散，同时可以避免高阶差分导致的低计算效率。
