Hi people,

i have two different mesh. One is 500k and the other is 2milyon. i have managed to solve the 500k with different turbulence models but when it comes for 2 milyon i cant.

- i both tried first and second order for all terms but it diverged.
- i changed the limits for temperature and pressure because it was giving the limitation error but it didnt work.
- i changed the underrelaxation factor but also it didnt changed.
- i finally changed the models but either it didnt work.

What could be the problem i am having any suggestions?
