Compressible Flow - Fanno Flow.
 

Hello everyone, I'm Rodrigo,
This is my first intervention in the forum.
I'm doing compressible flow simulations, Fanno flow with Ansys, and I need to do the same with OpenFoam software.
I really do not know what solver, or how to start using it, could you please help me?
Thank you very much.

Hi Rodrigo,

I suggest you to look at the tutorials. If you have installed OF v5 properly you can directly type in your terminal "tut" and you are in:
"/opt/openfoam5/tutorials"

For your case I will start to study an incompressible steady state case (solver: "simpleFoam") like for example:
"/opt/openfoam5/tutorials/incompressible/simpleFoam/pitzDaily"

Afterwards you can study compressible steady state cases, because for you I guess "rhoSimpleFoam" is the solver you need.

Regards.

Thank you very much for your answer,

I started doing all the tutorials. I used the recommended solver, my biggest problem (in all my simulations with OpenFoam) is to correctly set the boundary conditions.:confused:

Please, I need a lot of help. Attached image of the case that I am trying to simulate.

Thank you.
