请教各位老师和同学们：
一、由于计算的流体域形状比较复杂，所以尝试用Ansys划分流体域网格，在Ansys中对流体域进行分块，对复杂形状部分进行网格加密，并且在复杂部分采用四面体网格进行贴合。最终网格数量在八百万左右。通过转化后形成openfoam的网格，在checkMesh中出现网格报错信息。下面为checkMesh的输出信息。请教老师和同学们这种情况如何去调整网格，或者这种网格会影响计算的收敛性吗？

二、在Ansys对流体域划分网格的过程中，由于需要局部加密，将流体域分为若干块，但整体网格共点。将该网格导入openfoam并转化后，发现识别出来的每个面为当时分块时每个块的外表面，这种情况无法进行边界条件的设置。请教各位老师和同学，如何在Ansys中，对整体流体域的各个外表面进行标注，可以在导入openfoam后找到标注的面进行边界条件设置。

下面为后续的报错信息，辛苦各位同学和老师，感谢！！！

请教各位老师和同学们：
在一个三维复杂流体域案例的计算中，部分流体域形状较为复杂，网格采用snappyhexmesh生成，网格数量六百五十万左右，checkMesh结果OK，边界设置检查无误。计算到30s左右时出现不收敛的情况。下面为计算过程输出信息中的最后的几个不收敛时间步以及最后的部分报错信息（因为字符限制，后续部分在评论中）。请教各位老师和同学们，报错信息表示了计算模型哪方面的问题以及如何去调整。

@李东岳 了解了，谢谢东岳老师

@myjimp
你好，请问snappyHexMesh并行剖切网格后如何将网格合起来呢？

在找资料的过程中发现了关于sampleDict中可用type的说明，包括uniform, face, midPoint, midPointAndFace, curve, cloud（之前在苏军伟前辈的博客中看到过相关介绍，但当时并无curve类型）。

可以看到是有针对曲线的类型(curve)，但是没有给出具体的做法，后面会尝试用这个提取一下曲面上的压力看看。

各位前辈好，想请教一下有没有类似midPoint这种提一条线上各单元物理量的方法，来提取像下图这种曲面上的各个单元的物理量，例如压力p。
（虽然用cloud方法也能提出来，但需要一个个找曲面上的单元坐标，单元多了的话感觉会相当麻烦 ）

@cfd_上弦月 已经解决了，点击左侧的选项''Zone Style''，确定内部流场对应的zone（以上面的图片为例，我这里是Step 1737 Incr 0）。选择''Surfaces''标签，然后在''Surfaces to Plot''处右键选择All surfaces，内部的流体域就能显示出来了。

@huoyanxiadebing 在 说实话，根本不知道选择什么湍流模型 中说：

看到你的帖子，发现你做的都是外流场，对于外部流动，沿表面位置分布的雷诺数大于500000时，通常认为流动状态为湍流；沿障碍物的雷诺数大于20000时认为流动状态为湍流，如果你的模型中雷诺数不是很大的话，你用层流模型计算即可，这就是有时候你用层流模型算的比较准确的原因；对于雷诺数的计算，最重要的一点就是你要选好特征长度，对于没有结构物时，你要以水槽的长度或高度来算雷诺数，加上了结构物，就要判断是否产生了湍流现象，以结构物的某个长度及其附近的速度来计算雷诺数。

前辈您好，请问这里提到的两个临界值是否有相应文献的支撑？

如果要计算防波堤（例如沉箱防波堤和水下防波堤）附近的雷诺数来选取相应的湍流模型（适用于低雷诺数或高雷诺数的），这个特征长度应该取防波堤的高度吗？对于二维和三维情况，特征长度的选取是否有不同呢？

另外，结构物附近的速度是否有较为通用的估算方式？对于防波堤附近的速度，能否用基于浅水波理论的公式Uh=cη进行估算呢（水深h，波速c，自由面高度η）？

书已收到，感谢东岳老师！
