Hello everybody !

I have a problem when I’m trying to create symmetry zones in the Meshing of ANSYS v16.1.
I already read a lot of help about this topic, but I didn’t find out how to solve my problem.

The geometry that I want to make periodic is quite complicated, so I finally came back on a simple cube in order to better understand how to create these symmetry zones.
I have a fluid inlet and outlet which are facing each other. Meanwhile I want to get a symmetry on the two others pairs of faces (top and bottom, left and right), in order to create two periodic zones in Fluent.
I managed to create in the Mesh two symmetric parallel faces without problem by using some methods: by symmetry areas, cyclic regions, or by match control, etc…

My problem is actually that I don’t manage to create two pairs of symmetry zones which are in contact at an edge. Two cyclic regions are working together (I mean the mesh is created), but the pattern on each faces is inverted (because of the rotation around the Z axis of a cylindrical coordinate system). It means, that when I go to Fluent, the number of cells match but not the patterns!
Finally, I have always the same error message: “The mesh could not be generated because two faces adjacent to an edge have different match controls applied to them. To correct this, ensure that match control settings are the same for both adjacent faces.”
I think I tried every combinations of match control and symmetry areas, I didn’t manage to solve that!
If someone could help me it would be very great J

Thanks!
