这样生成的网格并不是点对点，而是一边对应多点<br />

在OpenFOAM中的paraview中显示效果<br />
<img src="/assets/uploads/files/1592555363550-c00320e5-5893-4a47-b0ed-87b5ec8aaf97-image.png" alt="c00320e5-5893-4a47-b0ed-87b5ec8aaf97-image.png" class=" img-fluid img-markdown" /><br />
请教下，这样的网格，在OpenFOAM计算的时候，是否可行呢？<br />
谢谢~~</p>

老师，已经进行了对网格的1对2改进：<br />
<img src="/assets/uploads/files/1592640969441-1592640955-1.jpg" alt="1592640955(1).jpg" class=" img-fluid img-markdown" /><br />
在ICEM转化到OpenFOAM中时，在<code>ployMesh</code>文件夹中出现了<code>set</code>文件夹里面是一个<code>nonOrthoFaces</code>文件</p>
<p dir="auto"><img src="/assets/uploads/files/1592641089004-2f9e8f66-ef5b-49e9-8a76-ab6507f8729f-image.png" alt="2f9e8f66-ef5b-49e9-8a76-ab6507f8729f-image.png" class=" img-fluid img-markdown" /><br />
出现这种文件，是由于1对2网格导致的，和下图这种网格非正交的是不同的<br />
<img src="/assets/uploads/files/1592641582951-a262e836-9e44-4399-8255-2b270336b97e-image.png" alt="a262e836-9e44-4399-8255-2b270336b97e-image.png" class=" img-fluid img-markdown" /></p>
<p dir="auto">所以在我这个案例的<code>fvSolution</code>文件中</p>
<pre><code>PIMPLE 
{
    momentumPredictor   no;
    nOuterCorrectors    1;
    nCorrectors         2;
    nNonOrthogonalCorrectors 0;
    maxCo               10;
    maxAlphaCo          5;
    rDeltaTSmoothingCoeff 0.05;
    rDeltaTDampingCoeff 0.5;
    nAlphaSpreadIter    0;
    nAlphaSweepIter     0;
    maxDeltaT           1;
}
</code></pre>
<p dir="auto">是否需要把<code>nNonOrthogonalCorrectors 0</code>改为<code>nNonOrthogonalCorrectors 1</code>，或者其它地方需要进行改动呢？</p>

但是可能会引起很大误差，通常建议1对2，逐步过渡</p>
