Hello

As everyone knows the following equataion:

Absolute pressure=guage Pressure +Operating pressure

My geometry has 2 inlets and 1 outelt. The absolute pressures are as follows:

@ 2 inlets each, Pabs=3 bar
@ 1 outlet Pabs=1 bar

After getting the convergence, the contour plots of Pabs at the inlets are not showing Pabs=3 bar (as of my inlet boundary specification), instead it is showing Pabs=1 bar (equal to the outlet Pabs).

How is it possible? Does FLuent not take into account the equal pressures? Does it cancel out the equal pressures? or there is any problem in contour plots?

Please help
