Dear All I have a problem with modeling solar still in fluent I model it with mixture model and if I model it with laminar it will diverge and if I model it turbulent models I get "turbulent viscosity limit" error. what should I do? does anyone have idea or a case that he/she can send me so I can examine it? thanks Amir

snailstb is on a distinguished road
I met the same problem when I simulated wave generation. It puzzled me for a long time. After i changed some boundary conditions, it disappeared. Specifically. I gave large turbluent kinetic energy and dissipation rate in the beginning. suggest you initialize fluid with small turbulence.
good luck
