Hi I'm trying to do MRF analysis of two wind turbines placed in an array. So I created common stator (outer domain) and two rotating domain placed in line at distance.
I imported all the three mesh into fluent and do the simulation. Second turbine is in wake region. So I get an issue called Turbulent viscosity ratio exceed 1e5 in ....cells. Then my continuity goes on increasing. Can anyone suggest me, what I have to do , to decrease the continiuity. I even increased the limit value to 1e20. But still I'm getting this error |

I am not too sure if I am correct but here goes..
I too get this message for 1 or 2 cells and I think that this generally happens if you have sudden/sharp turns in you mesh. Say at the leading edge of your blade if you do not put enough number of points you will get sharp corners. Like i said not too sure abt this, hopefully this will help. |

HI...I am trying to simulate a horizontal axis marine turbine in Fluent.
In reference value section, Is the area= rotor swept area and length= rotor radius? Thanks in advance |
