The grid generation technique, difference scheme of convective and diffusive terms, pressure and velocity correction methods and arithmetic of nonlinear equations are determined.
Only velocitygrid 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.
