turbulent viscosity
 

Hello,
I am solving an unsteady problem and I get the warning message:

turbulent viscosity limited to viscosity ratio of 1.000000e+05 in 1 cells

which appears once at every 10 to 20 time levels. This disappears after some iterations but keeps popping up at new time levels.

My question is, given that this happens only in 1 cell and that the message disappears after further iteration and it only occurs every 10-20 time steps, is it a critical issue?

Thank you.


Cheers,
EH
