Hey,

i am trying to connect 4 patches of my geometry pairwise with the cyclic condition. I get the following Error:

--> FOAM FATAL IO ERROR:

FOAM parallel run exiting

more information about the case:

- the 4 patches are each on a different region. All of those regions will be later merged.
- the meshing is done in parallel, at the moment on 2 cores.
- the case is a CHT case (i have read something about Temperature coupling does not work with cyclic?!?)
- the snappyHexMeshDict/castellatedMeshControls/refinementSurfaces/total_domain/regions looks like that

  coolant_cut_left_upper
                {
                    level (0 0);
                    patchInfo
                    {
                        type cyclic;
                        neighbourPatch coolant_cut_left_lower;
                        transform translational;
                        matchTolerance 0.1;
                    }
                }
                 coolant_cut_left_lower
                {
                    level (0 0);
                    patchInfo
                    {
                        type cyclic;
                        neighbourPatch coolant_cut_left_upper;
                        transform translational;
                        matchTolerance 0.1;
                    }
                }
                 coolant_cut_right_upper
                {
                    level (0 0);
                    patchInfo
                    {
                        type cyclic;
                        neighbourPatch coolant_cut_right_lower;
                        transform translational;
                        matchTolerance 0.1;
                    }
                }
                 coolant_cut_right_lower
                {
                    level (0 0);
                    patchInfo
                    {
                        type cyclic;
                        neighbourPatch coolant_cut_right_upper;
                        transform translational;
                        matchTolerance 0.1;
                    }
                }

I have not used cyclic before. I dont know wheter its the right tool or something like the BC mappedValue would work better. Help is much appreciated.
Have a nice weekend!
