Boundary Conditions in Ansys
I am new to Ansys. I have a Problem setting the pressure conditions for my simulations.
Currently, I have a situation where air is flowing in at high pressure(2-7 bar) and flows out into regions with atmospheric pressure conditions.
Do I have to set the reference pressure in the domain to 1 atm ?
I ask because when defining the boundary conditions the program asks about the 'relative pressure'. What is that supposed to mean ? does it caluculate the pressure relative to that 1 atm in the basic setting or not?
I have read somewhere else, that setting the reference pressure to 0 atm will provide the absolute pressure calculated at the outlets.
Thank you very much !
