Multi Zone with ICEM
 

Hi, guys
I want to use MRF method to simulate a centrifugal pump,
I used ICEM to mesh its geometry,
According to fluent guide(Using Multiple Rotating Reference Frames)
I made 3 zones and meshed them seperately,
But the problem is that according to the guide after reading the mesh we will have shadows ( the wall between two intrior) and then we should change their type to interior,
but i dont have any shadow now!!!

I am not an expert at this, but if you imported them as separate files, you may just have two walls instead of a wall and its shadow. I think you can still turn those walls into "interior".
