差分网格
提出无限大流场中多体运动计算的动态差分网格。
As raster grid networks of digital elevation model in GIS can be used as the finite difference mesh, the continuity and momentum equations are solved numerically using the finite difference method.由于GIS中的栅格网络数据可以直接作为有限差分的网格,二维数值模型可用有限差分来求解。
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。
