STAR-CCM+网格转换后，checkMesh报错

[HatoriChise]

OpenFOAM小白，我在STAR-CCM+绘制网格完网格，用ccm26ToFoam转换到OpenFOAM中。
默认的的boundary类型如下，checkMesh是没有问题的

//
我把boundary修改成下面之后，checkMesh出现了如下错误，望各位大佬帮忙看看。

1.我猜是symmetry这个边界条件，试一下改成wall，然后在0文件夹里自己定义上下的slip边界条件。openfoam会对生成的网格编号进行检查，外部软件的网格节点编号和blockMesh的逻辑不一样。
2.可能是前后的empty边界问题，你可以在starccm里生成3D网格后，重新在openfoam里extrude来生成前后empty边界
类似这样
constructFrom patch;
sourceCase "../w3-d_hc1-3";
sourcePatches (symFront);

// If construct from patch: patch to use for back (can be same as sourcePatch)
exposedPatchName symBack;

// Flip surface normals before usage. Valid only for extrude from surface or
// patch.
flipNormals false;

//- Linear extrusion in point-normal direction
extrudeModel linearNormal;

nLayers 1;

expansionRatio 1.0;

linearNormalCoeffs
{
thickness 1;
}

// Do front and back need to be merged? Usually only makes sense for 360
// degree wedges.
mergeFaces false; //true;

// Merge small edges. Fraction of bounding box.
mergeTol 0;
