hi to all;
I am running a hybrid grid (near body strucured and unstructured in FAR FIELD)of about 4.5 million cells on fluent using SA-turbulence model, segregated, 3D. I have a problem with the convergence, after about 7000 iterations, it gives a problem of "TURBULNCE IN CELL NO ----- " something like that which causes the solution to diverge, bad qualtative results and quatitave as well. anyone who can help me solving this problem. |

check the following; 1) mesh quality 2) urfs for turb k e and dessipation rate 3) descritisation scheme
This things are responsible for the same |
