网格只是自动生成的……新手
谢谢！

计算模型的问题。

smilingforrest

solver 还是solution?

smilingforrest

先行谢过！

你要把问题描述一下，才好分析。

我是用gambit自动生成 的网格，因为怕网格太多计算过慢，只有18万个多点的网格。
然后用fluent，solver 用的density based, 打开能量方程，vicous选的是k-epsilon，然后算着就成这样了。

把你研究的问题，计算模型都说清楚。我们都不知道你的装置中流动情况。最好上图。

我上传的附件里有需要的文件，包括.igs，网格，.cas,dat。还需要其他的？

我们不会像那些庸医，来了就看你照的片子。我们要听你说。
