Hi all. i have a problem for with i need to model heat transfer with translational periodicity. i created a mesh and imported it in fluent and tried to make the zones periodic using the tui. i couldnt do is as the no. of elements on both the faces was different. so i mapped the mesh and tried it again but with no success. this time the error contained no information at all, it just said failed to create periodic zones. I need help. i have attached the images of geometry as well as the mesh and error.
