Pressure analysis of Stationary fluid
 

I like to analyse the pressure variation of a fluid across the vertical tube containing porous medium at the center. The fluid is stationary and pressure is given from top or suction pressure from the bottom. No velocity is present but gravity acts.

Can anyone share me the procedure in ansys fluent.?

You might want to try the fluent forum for Fluent specific questions.
I don't see why you need CFD for this?
DeltaP from your boundary pressure will just be = -(rho * g * DeltaHeight)
If the fluid is stationary, the porous medium does nothing.
