Specifiy boundary type
 
Hi, I made a model of a centrifugal pump, but what boundary types do i have to specify for the pump? So what should i do?

post few pics. Generally boundary conditions are

1. Inlet : Pressure inlet >>>>>>> specify total pressure and flow angles.
2. Outlet : Pressure Out >>>>>> Specify the static pressure required to produce the mass flow rate.
3. Blade and hub: no slip condition wall
4. Casing . Zero Velocity in absolute reference frame.
5. Periodic boundary : If modeled one or two passages.

Impeller speed
 
The impeller speed is 1300 rpm, how it specifiy?

cell zone condition >>>>>> Fluid >>>>>>>> provide rpm there with axis of rotation.
