i use an Eulerian model, and when i try to increased the volume fraction (B.C->velocity inlet-> volume fraction)

to 0.02, and make the initialized i get the next massage (before the running of the calc):
"turbulent viscosity limited to viscosity ratio of 1.00 e+5 in 27915 cells"

what it mean? do E model have a limit of volume fraction?

thanks

There is such limit on volume fraction. The mixture properties would have triggered turbulent viscosity to be very high. Try changing the inlet turbulent quantities.

Sorry its mistake, I mean there is no such limitation.

Change turbulence quantities in the inlet panel and you can check values in initialization panel or contour plot after initialization.
