我们给出了“哲学”,相当完整的说明,草图和例子,从简单到复杂的创建分离涡模拟(DES)网格,优先考虑外部流动。虽然DES不是一种分区方法,但出现了具有广泛不同网格要求的流动区域,如果要很好地利用网格点,则应尽可能容纳这些区域。这不是DES所独有的。我们将简要介绍时间步长的选择、简单的陷阱以及评估模拟是否得到很好解决的工具。
We give the ``philosophy'''', fairly complete instructions, a sketch and examples of creating Detached-Eddy Simulation (DES) grids from simple to elaborate, with a priority on external flows. Although DES is not a zonal method, flow regions with widely different gridding requirements emerge, and should be accommodated as far as possible if a good use of grid points is to be made. This is not unique to DES. We brush on the time-step choice, on simple pitfalls, and on tools to estimate whether a simulation is well resolved.
