Dear friends

I'm doing simulation about turbulent that happen in room. Existing boundary conditions is mass flow rate, pressure and density. But when i want to do the iterations, i have an error notification. That is :

iter continuity x-velocity y-velocity z-velocity energy k epsilon time/iter

reversed flow in 1 faces on pressure-outlet 8.
turbulent viscosity limited to viscosity ratio of 1.000000e+005 in 41946 cells

Error: Floating point error: invalid number

Error Object: ()



what is mean and how to solve this problem error?
i need your help to solving my problem.

Thanks.
