管道模型RAS并行计算中遇到的问题

[疾风GAVIN]

因为模型的网格量比较大，所以我选择并行计算，但在过程中遇到了一些问题，之前也没有遇到过，在论坛上向大家请教一下为什么这样？应该怎么进行修正？谢谢！

decomposeParDict

numberOfSubdomains  3;

/*
    Main methods are:
    1) Geometric: "simple"; "hierarchical", with ordered sorting, e.g. xyz, yxz
    2) Scotch: "scotch", when running in serial; "ptscotch", running in parallel
*/

method              scotch;

simpleCoeffs
{
    n               (4 2 1); // total must match numberOfSubdomains
    delta           0.001;
}

hierarchicalCoeffs
{
    n               (4 2 1); // total must match numberOfSubdomains
    delta           0.001;
    order           xyz;
}

运行的代码

mpirun -np 2 rhoSimpleFoam parallel

报错

--> FOAM FATAL ERROR: 
Wrong number of arguments, expected 0 found 1

FOAM exiting

-------------------------------------------------------
Primary job  terminated normally, but 1 process returned
a non-zero exit code.. Per user-direction, the job has been aborted.
-------------------------------------------------------
--------------------------------------------------------------------------
mpirun detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:

  Process name: [[65460,1],1]
  Exit code:    1

你用scotch分了3块，但是mpirun的-np是2。

我把它改成3之后还是一样的报错，后面我是了一下不并行进行计算，它显示的报错是
：

--> FOAM FATAL IO ERROR: 
inconsistent patch and patchField types for 
    patch type symmetry and patchField type symmetryPlane

file: /home/jifeng/OpenFOAM/jifeng-6/run/Isolater-Huang/Isolater-Huang_1/0/alphat.boundaryField.symmetryPlane from line 59 to line 59.

    From function static Foam::tmp<Foam::fvPatchField<Type> > Foam::fvPatchField<Type>::New(const Foam::fvPatch&, const Foam::DimensionedField<Type, Foam::volMesh>&, const Foam::dictionary&) [with Type = double]
    in file /home/jifeng/OpenFOAM/OpenFOAM-6/src/finiteVolume/lnInclude/fvPatchFieldNew.C at line 160.

但是我的alphat以及其他的初始条件以及polyMesh文件夹里面的boundary里面的symmetryPlane边界面都是用的是symmetry，不知道为什么它会说alphat里面会

inconsistent patch and patchField types for 
    patch type symmetry and patchField type symmetryPlane

[疾风GAVIN]

刚刚我发现原因了，对称面不能命名为symmetryPlane,不然在运行的时候会报错：

inconsistent patch and patchField types for 
    patch type symmetry and patchField type symmetryPlane

我把对称面改称sym后就可以开始计算了！

@疾风GAVIN symmetryPlane的要求好像特别严格，我以前也碰到过，后来再也不用symmetryPlane，一律用symmetry

[疾风GAVIN]

@cccrrryyy 嗯嗯是的，symmetryPlane要求对称面的normal必须一样，有些时候就算差的很小不影响计算，但是它也会报错的，我后面修改成symmetry后，发现并行计算也可以进行了，问题应该就是在symmetry和symmetryPlane的区别上。谢谢您～
