Hi,

I was puzzled by the Prssure:reference,relative,absolute.If I set the domain prssure 5000Pa,and the inlet Preesure 80KPa,which both are absolute pressure,How should I set the reference and ralative Pressure?

Thank you for your help. regards,

You could set the reference pressure of the domain in 5000 Pa and the inlet will have a relative pressure (80000-5000) Pa, that's to say, 75000 Pa. Do you understand? You could read "Setting a Reference Pressure" in the Modelling help.Good luck!

Hi,yolan

That is to say,Pressure=reference pressure +relative pressure .Am I right?

Got it,thank you. regards,
