Dear Foamers, I need some help.

I try to simulate flow in open channel with interFoam. I use setting from wigleyHull tutorial. I only changed the geometry of channel and inlet velocity (0.25 m/s). But I see instability in simulated results. Tel me please what need to change to get flow without instabilities. Screenshots of alpha, U and case setup are attached.

Thanks a lot!
Maxim
