Dear all

i am a new user of cfd, i would like to how important is the reference pressure location in CFD modeling ?

should i specify it in every problem?

thank all

Assalam Alaykum wa Rahmatullah

Use zero as reference pressure and then you dont have any need to define reference pressure location.

But remember that you have to use absolute pressure in boundary condition panel. But if you are using some reference pressure then you have to use gague pressure in bc panel
