问题：2021r2版本，在封闭形成流体区域的过程中，无法选择面。有哪位前辈指点一下吗

想找一些适合cfd入门学生学习的题目
最好有把cfd的各个环节单列出来的题目（例如 贴体坐标系生成）
以及这些问题用什么工具求解
我是指学习使用哪些工具对于科研实际具有意义（例如使用哪些软件（fluent？turbo？） 还是用哪种语言自己编写代码（例如cpp）？有哪些部分已经出现类库，哪些需要自己编写呢？尤其是科研中是怎样实际操作的）

对简单的长方体进行网格划分，再检查网格质量时发现在长方体的周围有很多有问题的face产生，也不知原因，很疑惑，求大神指点，万分感谢！

在计算单相流作为初场，可以收敛，但是湍流粘度比超限，继续设置为多相流空化计算的时候，开始发散，不知道有哪些解决办法，已经重新画过网格。
边界条件是速度入口，压力出口，湍流sst k-w，稳态计算

@RebelYoung 这种错误可能是数据本身有问题，不一定是paraview的问题。

如果想确定，可以去paraview的官网下载最新的paraview。如果连它都崩，那就是数据的问题。

最近有一个项目在meshing里最小正交质量已经提到0.15以上了，放到求解器中提示在0.01以下，有没有前辈有过这种问题？

@桎梏 :chitang: 不客气

请问这个计算几十步后出现的这个逻辑处理器满了后弹出的The f1 process could not be started，然后怎么才能继续运行呢？是无法计算了吗

兄弟，这个是树木简化为多孔介质吧，这个比较简单，不要用UDF就能实现，直接采用多孔介质模型就可以了，就是需要转化一下，多孔介质模型所填的阻力系数=2*LAD*Cd。另外，兄弟，我也是在做这个，我想在多孔介质区域加一个附加项，考虑树木对例子的吸附，会吗？欢迎加我讨论QQ1225220118

公式18分行了还是显示不下。
大家都怎么处理的？用的是latex
