How to export a field from the outlet patch in order to use it as an inlet boundary condition for another case in OpenFoam?

I would like to have a fully developed flow as an inlet boundary condition in my openFoam pipe flow case. For this, I performed another simulation and waited until the flow is fully developed. Now...

Is it correct to have a courant number more than 1 even if the simulation is stable enough in openFoam?

with kOmegaSST model, I am able to get a pretty robust simulation even when I have a high courant number, I was wondering if that will result in a correct answer. If yes, maybe I can get much...

Should I use a fully resolved LES in a pipe with flow separation using openFOAM?

I have in my Geometry some cavities with almost zero flow. I was wondering if openFoam comes with some embedded LES model that uses RANS in bulk flows and employs LES near the wall. If yes what is...

What boundary conditions should I apply to LES fields in OpenFOAM?

Hi all, So after failing to get satisfying results to my simulation using the RANS model, I decided to switch to LES. As I am expecting some flow separation, after reading some papers, I decided...

One model for different Reynlods numbers?

using openFoam, I have to compare the behaviour of the fluid inside a pipe flow at different speeds, that ranges from laminar to Turbulent flow. The problem here is that I need to stick to one...
