@wuyukai 大哥，你帮我看看这个，是不是也是这个问题呀？

https://www.cfd-china.com/topic/7801/paraview求助-操作出现问题了/5?_=1735889189654

谢谢大哥了

第3198到3208行代码

但是在另一台电脑上，两个版本都能用。裂开了。是不是这台电脑的什么文件不合适了？有没有大佬能指导一下，5555555555555555555555，裂开了。

这个是另一个版本的，提示的问题

各位大佬，想请教一下paraview操作的问题，突然无法运行了，然后重新下载了一个新版本，还是有这个问题，这个是运行时候的错误提示，能不能帮我指导处理一下，谢谢各位了。

烦请各位大佬指点一下，workbench里面mesh画的带角度的翼型的网格，为什么边界层厚度不一样啊？怎么处理一下呢？上面的感觉太窄了

@李东岳 李老师，就是感觉有时候，不能满足通过理论计算得到的边界层信息，比如不能满足边界层厚度啊，层数也达不到，这种一般怎么处理啊？感觉workbench的mesh虽然可以，但是我希望通过这个方式画网格，这样对我后续的计算方便一点。💋

snappyHexMesh画边界层，大家都是按照计算下来的层数，边界层高度画嘛？我按照计算下来的，层数一多就画不出来啊，就是很简单的翼型绕流的，有没有大神有相关的心得体会之类的，可以交流一下嘛~

@李东岳 好滴，谢谢李老师~

发现这个参数匹配好麻烦啊，层数、第一层高度等等之类的，感觉按照计算得到的画一下基本不出来

大家好，请教一下各位专家老师，就是我用这个snappyHexMesh画一个翼型的边界层时，出现了部分区域生成边界层，部分区域没有边界层的现象。

想请大家指点一下，这是什么原因呢？可以通过哪些方面的调整解决这个问题呢？谢谢大家。

您好，请问解决了嘛？我现在也碰到了同样的问

@huiyin 谢谢~

谢谢谢谢~么么哒~

@Prometheus10

期待期待

我是个小白啊，感觉有时候处理这种空间后，反而打不开了，所以还是买硬盘吧
