Hello Fluent users,

If my operating presure is 0.3 Mpa, how and what should i set my initial pressure at inlet boundary condition and gauge pressure's at outlet condition ?

If i static pressure is 98,000 Pa at outlet, how and what should be the inlet and outlet pressure conditions in fluent.

I am confused with FLUENT pressure settings. Please help me how to understand these pressure's in FLUENT

Thanks and Regards
-- Sampath Emani

Absolute pressure=gauge pressure+operating pressure
Total pressure=static+dynamic

If your model is on nature pressure you can use default in operating pressure and 0 for gauge pressure. In this situation your model is nature with 101325 pa pressure.
