Turbulence modelling error

Hey guys,
I am a newbie and I was trying to do a turbulence modelling. The flow is inside a large duct and the velocity is very high. I was modeling the 2d case and prepared a udf for inlet velocity, dissipation rate and turbulent kinetic energy as explained in the user guide. As i started the iteration, even before it goes through the first iteration, it gives me this error: turbulent viscosity limited to viscosity ratio of 1.000000e+005 in 341000 cells I tried to change the limit of viscosity ratio to a higher value, but still it gives me a similar error. Any thoughts? Thanks in advance, Derick |
