Hi!

I have a question.

Iīve done a rectangular mesh. It represent the atmosphere.

The underside represent a big surface (Boundary condition: wall)

The other sides represent the boundary of the atmosphere.

I want to fix standard conditions for temperature and pressure.

What is the Boundary condition for sides that represents atmosphere?



Thank you very much!

Set "Operating Pressure" to "zero" and set the boundary condition for that side as "Pressure Farfield" and set guage pressure to "101325" and temperature to "288.15". Hope it helps
Regards
