hey,
you don.t need to worry much about that line... it will be disappeared with respect to iterations. I ran many simulations on species transport ( non reacting). At iterations stage below 100, you might find that. But later, it will be calculated and disappeared Regards, Sampath Surya |

So,
if you are still getting theses messages after long simulation time then you have a problem in your setup. Increasing the value to such a high holdup and still getting these warning this depicts that something is wrong or the turbulence model which you are using is false or you have very big eddy length scales. Please post your settings setup (turbulence model /turbulence inlet sepcifications, Boundary Conditions, Picture of your problem) |

and changing the limits in solutions does not effect your problem. i mean, turbulence viscosity limitation. JUst run more iterations .. you will not see that line anymore.
That appears due to the boundary condition values. I mean, the values and properties you gave might not be that accurate. |

WE have to change the limits if we are simulating a large/full scale geometry!!!
But your are right he has to share with us his model specifications! |

The mesh contains high aspect ratio quadrilateral,
hexahedral, or polyhedral cells. The default algorithm used to compute the wall distance required by the turbulence models might produce wrong results in these cells. Please inspect the wall distance by displaying the contours of the 'Cell Wall Distance' at the boundaries. If you observe any irregularities we recommend the use of an alternative algorithm to correct the wall distance. Please select /solve/initialize/repair-wall-distance using the text user interface to switch to the alternative algorithm. |
