Hi everybody,

I've created my 2D mesh with Gambit and select two boundary as periodic BC. Then I converted it with fluentMeshToFoam. my periodic BC name was 'periodic' and actually it contains two edges of my model. I used foamUpgradeCyclics and my bc splited to two BCs:

Code:
periodic_half0
{
    type            cyclic;
    nFaces          93;
    startFace       50116;
    neighbourPatch  periodic_half1;
}

periodic_half1
{
    type            cyclic;
    nFaces          93;
    startFace       50209;
    neighbourPatch  periodic_half0;
}
then I modified the files in 0 case.

but when I ran paraFoam and want to see my meshes the below error appeared:

Code:
--> FOAM FATAL ERROR: 
More than six unsigned transforms detected:
6(((4.8172043e-05 0.00028 0) (1 0 0 0 1 0 0 0 1) 0) ((5.41935484e-05 0.00028 0) (1 0 0 0 1 0 0 0 1) 0) ((6.02150538e-05 0.00028 3.32344303223e-24) (1 0 0 0 1 0 0 0 1) 0) ((6.62365592e-05 0.00028 0) (1 0 0 0 1 0 0 0 1) 0) ((7.225806455e-05 0.00028 9.50757114744e-24) (1 0 0 0 1 0 0 0 1) 0) ((7.827956985e-05 0.00028 -1.28310141797e-23) (1 0 0 0 1 0 0 0 1) 0))

    From function void Foam::globalIndexAndTransform::determineTransforms()
    in file primitives/globalIndexAndTransform/globalIndexAndTransform.C at line 185.
