I have another doubt, if i use pressure outlet at exit and specify the exit pressure at the outlet to 0Pa, the how the pressure at exit is calculated? Is the pressure is fixed? or like in outflow the pressure at boundary is calculated using the precalculated values from upstream cells? What is the difference in fluent Enterprise, premium, pro? Is there any difference in solver algorithms? I am using Fluent enterprise.
