How to transform the Cylindrical turbo surface into flat surface in cfd-post?

Hellow,i am interseted in the velocity of the centrifugal compressor impeller outlet. But,i can't get the flat surface at the outlet of the impeller.I just know to get a turbo surface at the impeller outlet. So,does anyone how to do it in cfd-post?
Thank you !!!

This sounds like basci post processing and is well covered by the tutorials. Have you done the tutorials?

Does anyone know how to do it?
I am hungry to know that.

You can specify a plane over your outlet and draw the velocity over this plane.

Yes,i know that . I insert a turbosurface and specify the variable. But ,the plane is cylindrical. What i want is a flat plane. So,my problem is to transform the cylindrical into a flat plan. Do you really understand what i want to do?

No, I do not understand what you want to do.

Do you want to put a flat plane through your domain, or do you want to take the existing cylindrical section and map it to a flat surface? Or something else?

I want to take the existing cylindrical section and map it to a flat surface.
I will show you some pictures which is the experimental result.
I want to compare my numerical result to it .http://ww2.sinaimg.cn/bmiddle/76f466...2tqw6uvn0j.jpg

I cannot think of a way of doing this all in CFD-Post. I would export the data from your cylindrical surface and plot it using an external package, like matlab, excel (if you must), python, tecplot or whatever you wish.
