Hi Zahid

It means that you have some elements with large volume, therefore I suggest that you plot a turbulent viscosity ratio contour and then change the auto range to a value between 10000 and 50000. In this way you will see where are the elements that are touching the turbulent viscosity ratio.

Once you identifiy the cells, refine these elements. In this way the velocity diferences between two adjacent cells is not to high to give you the warning turbulent viscosity limit 1e05.

Regards
