你好，我也在做这一项工作，请问您现在寻找到解决该问题的办法了吗？

请问各位大佬，OpenFOAM v1912中怎么植入FPVFoam(新手）

@liurui 面的编号要用右手定则指向计算域外侧，所以就比如第一个hex应该是（0 7 6 1 8 9 14 15）

您好，请问解决了嘛？我现在也碰到了同样的问

@huiyin 谢谢~

@学流体的小明 好的，谢谢

@李东岳 感谢老师回复！动量预测是关掉了的。

打开试了试，步长极小，残差也一直保持在一个值不下降，cumulative则很大，如下：

看到站内其它的帖子，试了试有量纲/无量纲计算（此前圆柱直径0.05，nu=50；改为圆柱直径0.0005，nu=0.5），也无法收敛。

走投无路试了一下StarCCM，多低雷诺数都能算，和OpenFOAM那些能收敛的算例比得还贼好

各位好，我现在设想一个工况是在水深非常浅，同时水深与船舶吃水非常小（大约1.2）的情况，在设置重叠部分也即船舶部分网格时，blockmesh需要画的比较小，底部与船舶底部很接近，这就造成了snappyhexmesh后船舶下部的网格质量很差，请问有没有什么办法或者思路来改善网格质量呢，如有相似问题的朋友欢迎讨论，谢谢!261e3ad06976a58e400a1fc15243dc1.png 78823dc1464db8ab58735e54dcd17d2.png efa88c4c50ed4254badb8dbc8db3089.png

@学流体的小明 好的，非常感谢解答

我也在算类似的问题，是不是给定进口水位和流量的设置方法不对

用interFoam计算带自由液面的倒虹吸，参考其他人边界设置，往往是入口给定流量（流速），出口给定水位（alpha.air)。这种设置方式如果通过手动设置（setFields)往往因初始流场不好极易发散，有没有办法能跟Fluent一样通过混合初始化得到一个初始场保证计算能够进行下去。（openFoam好像可以通过potentialFoam初始化场，但是这个对于interFoam也可以使用吗）79538e5a-b907-420a-8777-c7a72dd6011f-image.png

@cccrrryyy谢谢前辈

你好，请问你编写的NSRFG，在使用时计算域是多大，网格尺度是多大，能否在整个计算域上保持低耗散甚至无耗散么

参考之前大神发的帖子就可以解决了
https://www.cfd-china.com/topic/6750/mapfield报错

@jxzs_zy 在开发，好像还没正式发布。Added dynamicPolyRefinementFvMesh

问题找到了，对于这个算例，在滤波尺度的选择中，不能够使用剪切层调整亚格子长度尺度修正，但是别的文献中有人使用过，目前没有找到原因。

你好，请问这个问题解决了吗？

您好，您解决了吗

您好，您解决了吗

@BznW 您好。打扰一下，您解决了吗
