周期性边界条件cyclicAMI的问题？

东方白杨

各位大佬，我设置了Mesh的边界为cyclicAMI

   inlet
    {
        type    cyclicAMI;
        inGroups    1(cyclicAMI);
        nFaces          1200;
        startFace       254800;
        matchTolerance  0.0001;
        neighbourPatch  outlet;
        transformType   translational;
        separation      (-7 0 0); 
        //method          faceAreaWeightAMI;

    }
    outlet
    {
        type    cyclicAMI;
        inGroups    1(cyclicAMI);
        nFaces          1200;
        startFace       256000;
        matchTolerance  0.0001;
        neighbourPatch  inlet;
        transformType   translational;
        separation      (7 0 0); 
    }

那么在0文件中U、k、epsion、p该怎么设置呢，我把inlet/oulet都设置为了cyclicAMI，

    inlet
    {
         type    cyclicAMI;
    }
    outlet
    {
         type    cyclicAMI;
    }

但是一运行就报错，我想问一下，原来给定inlet的fixvalue，outlet的0梯度，在设置为cyclicAMI type后，这些进口速度什么的去哪给定呢？是在internalField uniform 0.015;这里吗？？？

报错如下：一改cyclicAMI就会报这个bounding k epsion问题

我在想本来k epsion给定的type是
type nutkWallFunction;和 type kqRWallFunction;
如果改成cyclicAMI，没有了壁面函数，会不会是因为这个导致k epsion报错？？？该怎么办呀。。
