AM not sure about this....but this may work....

There is something called CEILING and FLOOR values set in Fluent..
Its there in the one of the menus ... may be SET sub menu or something.

Change the value of ceiling ....

Thanks vegad...

I searched for CEILING and FLOOR values set in Fluent, but I could not find them..

There is limits option in fluent under solve--control, where we can actually change this limit values... However, solution obtained by changing this values are not accepted.

I want to know the reason behind this error.... turbulent viscosity limited to viscosity ratio of 1.000000e+005 in 23717 cells, this error arise because of mesh quality or some thing else...
