I cannot see how you can model a centrifugal pump in 2.5D, as I understand it.

Also - this is the CFX forum, for questions about Fluent try the fluent forum. But your question seems to be more about post processing anyway.

im sorry, i meant to say that i made a 2D centrifugal pump but extruded it in the z direction. i did this because the volute width and the impeller width were different.
sorry for the confusion

What Post Processor are you using?

i use fluent post for finding head and use cfx post for velocity and pressure

We cannot help you with the Fluent post processor, try the fluent forum for that.

But we can help you with the CFD-Post post processor work (despite this model being done in Fluent).

Please post an image of what you are modelling and show where you are having the problem and what you want to see.
