Hi!

I'm trying to create a Mesh for a circular plate. The goal is to simulate the distribution of a fluid which enters the plate from a hole in the middle.
I have some problems with the cyclic boundary condition! The Mesh itself doesn't look so wrong. It should be 90 degree of a full circle.


But if i do a checkMesh, i get the following 2 errors:

Mesh non-orthogonality Max: 179.858 average: 14.9863
 ***Number of non-orthogonality errors: 4000.
**Error in coupled point location: 2000 faces have their 0th or consecutive vertex not opposite their coupled equivalent. Average mismatch 0.
  <<Writing 2000 faces with incorrectly matched 0th (or consecutive) vertex to set coupledFaces

Failed 2 mesh checks.

Here's the content of my blockMesh File:

vertices
(
    (0 -0.1 0)  //0    
    (0.5 -0.6 0)  //1    
    (0  0.1 0)  //2
    (0.5  0.6 0)  //3
     
    (0 -0.1 0.01)  //4
    (0.5 -0.6 0.01)  //5
    (0  0.1 0.01)  //6
    (0.5  0.6 0.01)  //7
);

        (0 1 5 4)   
        );
    }
);
mergePatchPairs
(
);

Did i understand it right, that the "rotationAxis" value is the direction of the axis, and the "rotationCentre" value the position of it?
I already tried to change the axe positions, but i get the same error. Probably it's a easy fault, like a syntax problem, but i can't find it. Can anybody help me?

Thank you!
