How to set a constant pressure of 90 psi in transient simulation in fluent?
 

Hello,

I am simulating the heat transfer between hot air and an aluminum solid inside a pressurized vessel in Fluent. I have defined a velocity inlet and pressure outlet in my boundary conditions. In reality, the solid is cured at a constant pressure of 90 psi. I want to reproduce this, but I am not sure what to input in my boundary conditions to insure a pressure of 90 Psi throughout the simulation. There is an inlet gauge pressure, an outlet gauge pressure and an operating pressure, but I am not sure what to input in each one, and I would really appreciate any help! I am doing a transient simulation by the way. Thanks
