Hey Syavash,
It is clear from the code that solver running time highly depends on the number of times the pressure correction step is implemented. Do you think that there is a way to reduce the number of the pressure correction step while maintaining the 4th-order RK projection for the velocity field? For example, if one only evokes the pressure correction at the end only once or twice between intermediate time steps. Thanks |

I can only think of the 3rd-order Runge-Kutta as a reply, which is of-course 3rd-order accurate in time but demands fewer number of pressure correction steps. I have already implemented that and it was faster, but don't remember it gave a huge difference over 4th-order Runge-Kutta. Best Regards, Syavash |
Well, I have uploaded both solver and its test case on my Github repository. On my reposityory, one can also find a bunch of useful codes WRT incompressible LES in OpenFoam.

Hey Syavash,
In your opinion, can the RK4Foam solver be used for an FSI study? I would like to explore its application for FSI studies with LES turbulent modeling. |
Hi Ville,
i tried to implement a fully explicit RK4 scheme for compressible flows (Euler Equations) , following your paper, but it seems that not work ( some waves are created near the boundaries ) Can you give me some explanation about that, thank you. |
