That's what I tried as well, but also got unstable results, depending on the mesh. Therefore I did not use it. @ cfd_user2011: Concerning setting the velocity in air to zero: You have to modify...

Pablo, it did not really improve the simulation with regard to smaller time steps and high velocities in the air phase. Depending on what you want to do and if the air phase is not of great...

Thanks Alberto, I guess you saved a lot of my time! I tried both schemes, and both simulations are working. The Gauss limitedLinearV 1 seems more reliable and accurate to me. Nevertheless,...

Replies: 37 Artificial high velocities at the interface using interFoam Views: 15,836 Posted By Arnoldinho Artificial high velocities at the interface using interFoam Hi all, I'm simulation flow of water around an object using the interFoam solver and k-Omega SST turbulence model. At the moment, I'm struggling with some artificial high velocities which occur at...
