Actone-Zero New Member Join Date: Jan 2010 Posts: 8 Rep Power: 16	Hi everyone, I am modeling a cavitating flow around a hydrofoil using starccm+ and I'm searching a way to modify the turbulent viscosity using a field function I have already defined. It is function of the volume fraction of vapor. The aim is to decrease the eddy viscosity in the closure region of the cavity Is anyone have ever done that before? thanks.
