Blocking of impeller single blade sector (MRF)
I'm stumped on the strategy to use to block a single blade sector model of a centrifugal pump impeller. The sector has a single blade, a piece of the casing and shroud. I know there has to be an O-grid around the blade but how do i include blocking to capture the Shroud and casing as well.
I know i need to upload pics but unfortunately i cannot.
Any advice would be extremely helpful

Thanks & Regards

Then upload a sketch...

Is the blade rotating within the stationary casing and shroud?

Often we would put a cylinder between the two (to represent the rotational interface) and block each side separately and then combine them in the solver. Does that simplify things enough for you?

Best regards,
