新写的程序单核计算无问题，但无法并行计算？
-
CFD的大佬们：
最近我基于interFOAM和sixDof模块写了一个关于动网格的程序，并将动网格计算的结果作为pimple外循环的判据，这个程序在单核的情况下运行没问题，结果也正确，但是无法并行，只要一并行就会出现类似这样的错误：
[1] --> FOAM FATAL IO ERROR: [1] incorrect first token, expected '(', found on line 0 the punctuation token ':' [1] [1] file: IOstream at line 0. [1] [1] From function Foam::Istream& Foam::operator>>(Foam::Istream&, Foam::List<T>&) [with T = Foam::Field<Foam::Vector<double> >] [1] in file /home/wdx/OpenFOAM-6/src/OpenFOAM/lnInclude/ListIO.C at line 131. [1] FOAM parallel run exiting或者这样类似的：
[1] --> FOAM FATAL IO ERROR: [1] incorrect first token, expected <int> or '(', found on line 0 the word 'g' [1] [1] file: IOstream at line 0. [1] [1] From function Foam::Istream& Foam::operator>>(Foam::Istream&, Foam::List<T>&) [with T = Foam::Field<Foam::Vector<double> >] [1] in file /home/wdx/OpenFOAM-6/src/OpenFOAM/lnInclude/ListIO.C at line 148.

[8] FOAM parallel run exiting我看了一下提示，发现是输入流的问题，具体错误我也定位出来了，是在计算库朗数时（CourantNo.H）：
scalarField sumPhi ( fvc::surfaceSum(mag(phi))().primitiveField() );我觉得这个错误的原因就是我将pimple.loop()改为了其他的判据，但是我看了pimple.loop()执行的内容，也尝试自己在程序中添加类似的内容，没有效果。
总的来说，目前的程序是单核运行没问题，但是并行会出错，并且一旦外循环的次数超过字典文件中指定的次数，错误就发生了（由于算法的前两个时间步要用到pimple 外循环所以pimpleOuterLoop这个数字还是要给定的，我给的是5）。
我最疑惑的地方就是为什么我单核的时候计算完全没问题，一并行就出现问题？对并行的机制不是很懂，求大神帮帮忙，不胜感激！
