Starcatcher Member Andy Join Date: Jul 2017 Posts: 62 Rep Power: 9	Hi folks, this is my case: driftfluxfoam, 3D-mesh with very good quality, alpha.sludge inlet 0.0024 buoyantKEpsilon turbulence model I tried this setup with a slamm mesh (sudo-2d), no problem When i try it on a bigger mesh ca. 4mio cells, the simulation diverges in the epsilon-transport equation. setting turbulence to laminar solves the issue. What could be the reason? I really would like to use turbulence here. Thank you
