Hi everyone,
I need your help! I thank you in advance for spending your time. I am a new user of openFoam and I am not very experienced. I need to build a new BC on outlet pressure. The pressure that I must impose depends on the value of the outlet flow rate. Can you give me some indication of how to start? Or is there something similar already implemented?

Hi I have some links for you:

A whole bunch of examples and a good start for OF programming, also BC:

http://www.tfd.chalmers.se/~hani/kurser/OS_CFD/

and

https://wiki.openfoam.com/index.php?...eeks%22_series

I also like the tutorials of wolfdynamic, there are some good examples for codeStream and the use in BC:

Search also for forum post like:

Custom Boundary Condition with OpenFOAM

That is by no means complete, but a good start I think.
