Hey there,
I am simulating the filling of a tank with interfoam and try to use k-Omega-SST model for turbulence. The mesh has around 400.000 cells, checkMesh says okay. Unluckily I encounter these errors a lot (sometimes after 0.25s, with different transport properties after 0.4s): Code:

I guess I have to supply my fvSchemes, fvSolutions and my initial conditions to trace this. My guess is a connection to the k-Omega-SST model. Probably my initial settings are bad, but I calculated them several times following the wiki here and can't manage to get it work. Case is currently starting laminar, if this works I will update you asap. U Code:

If somebody spots a mistake in one of the files please tell me! I am super lost with this. All help is highly appreciated! Big thanks and best regards! I hope somebody with more experience can help me to fix this, unluckily it's a bit urgent for my thesis. Greetings! Simon |

Hey,
I checked a lamniar case. Same error but at a different timestep Code:

Hey Simon!
Have you perhaps solved this issue? I'm also trying to run interFoam with the kOmega model and also don't know which solvers and schemes to use, since the tutorial of kOmegaSST exists only for the LTSInterFoam. Have you figured out the right solvers and schemes? thanks for the help, Matej |
