Hi,

I just started with starccm+ and when i was running my simulation, I noticed that there was this one line:

Turbulent viscosity limited on <xxx number> cells in Region

What does this means? Will it affect the simulation? How can it be addressed?

It usually means your grid isn't fine enough or you have BC issues. Plot turbulent viscosity and see where it's limited.
