Hi, i am new to ICEM and got some problems of creating a functional mesh.

the case: I want to simulate a channel with a cube in it. There are only walls at the top and the bottom of the channel. Rest of the surfaces need to be cyclic. I want use an unstructured mesh with prism layer at the walls and the cube. Afterwards the problem will be exportet as fluent_v6 and solved in openFoam.

The problem is, that the mesh of the cyclic patches dont match to the respective partner patches.
I tryed to mirror the patches. But then, the new surface mesh doesnt fit to the rest of the mesh und icem wants to correct this.
Can someone explain me how to generate an unstructured mesh which is able to use cyclic boundary conditions?
