Periodic Boundary Conditions

I am trying to set up my simulation in Starccm+ and want to use a periodic boundary condition. I have looked at the possible options and there is a symmetry plane but this is not what I want. This gives a solution that is symetric on one of the planes. My solution is not symetric but I want it to be repeated over and over again.
It is a compressor blade on a disc and I want to simulate just one blade and then use a periodic boundary condition to simulate the rest of the blades on the compressor disc. Does anyone know if this is possible? Thanks |

You need to use a periodic interface. Select the two boundary faces that are going to be pairs, and create a periodic interface from them. After that you can expand the interfaces, and make the interface a rotational periodic interface and specify the axis of rotation. If I'm not mistaken when you generate the volume mesh StarCCM+ will check the interface to see if the two faces are truly periodic and then populate the angle of rotation.
