HI,

I am simulating a radial turbine impeller simulation using openfoam.
I have periodic boundaries as i want a passage to be simulated.
createPatchDict looks like

FoamFile
{
    version     2.0;
    format      ascii;
    class       dictionary;
    object      createPatchDict;
}

// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

matchTolerance 1E-3;

pointSync true;

patchInfo
(
    {
        name ROTOR_PERIODIC;
        dictionary
        {
            type cyclic;
        }
        constructFrom patches;
        patches ( PERIODIC1 PERIODIC2);
    }

);

When i run createPatch command ..
I will get the following error

Reading createPatchDict.

Create polyMesh for time = 0

Adding new patch ROTOR_PERIODIC as patch 8 from 
{
    type            cyclic;
}


--> FOAM Warning :

    in file directTopoChange/directTopoChange/directTopoChange.C at line 2281

What could be the problem ?
