Turbulent viscosity ratio -- CFD Online Discussion Forums

January 28, 2003, 11:40	Turbulent viscosity ratio	#1
Jurgen Guest Posts: n/a	I am using the standard k-e turbulence model in a quite large grid, about 1 mio. cells. I cannot improve the number on grid cells anymore. During iteration, I get the message that the turbulent viscosity is limited to a viscosity ratio of 1E+5. I know how to change this limit, this is not the point, more how to deal with this problem. Besides, the solution is converging very (!) slowly. Any ideas someone? Regards, Jürgen
