Dear Fuxin,

The 0 material number has no influence on the simulation, so you don’t need to check it.

I have now set the Resolution of 50 and the charPhysU I set in the converter instead of 1 m/s. In this case the simulation remains stable. But if you want to make a real LES I would calculate a finer resolution, check the Kolmogorov scale by the current Reynolds number and make the resolution 3-10 * Kolmogorov.

Best regards
Fedor
