Unhappy Initial Condition for expanding Air

Hey fellows!

I would like to simulate a pressurised outlet stream of air. In the simulation I'll have some kind of a container filled with an overpressure of 2 bar air and I would like to simulate the airflow through an outlet nozzle. My problem is, that I cannot set the initial pressure just for the region where the container is located. It is no problem at all to set every cell to this pressure, but I have to visualise the flow behaviour outside of my nozzle where the pressure is 2 bar less.

Any suggestions?

Hendrik

Hi,

Short answer with some hints.
I would suggest to search for setFields, or funkySetFields (from swak4Foam).

Regards,
Tom
