Cyclic periodic for fan impeller -- CFD Online Discussion Forums

Fouch Member Join Date: Feb 2020 Posts: 79 Rep Power: 6	Hi everybody, I am working on centrifugal fan simulation. To save computational cost, I want use cyclic periodic boundaries but I am not sure how to proceed. Currently, I run my calculation with AMI on a full impeller. I modify the 3D model and the AMI to have only 1 blade. But I don't really know which files I have to modify. I think the main job will be on createPatchDict ? If anybody has a tutorial or a file example ? Thank you !
