The grid generation technique, difference scheme of convective and diffusive terms, pressure and velocity correction methods and arithmetic of nonlinear equations are determined.
确定了本文数值模拟所采用的网格的生成技术，对流扩散项的离散格式，压力修正与速度修正方法，以及非线性代数方程组的求解方法。
Only velocity grid values have the additional solve steps applied. This option may avoid some artifacts that can result from high detail on the density grid.
只有速度网格值有额外的步骤出现，这个选择能避开一些…并在密度网格上产生高细节。
We take a triangular grid, where velocity and position parameters of each grid-point must be given.
