Hi
Turbulence modelling is available in vof, but its not suitable for multiphase problems. e.g I had simulated flow around a ship using VOF, k-epsilon model and I found that resistance was over predicted. It was more then twice the experimental value. Laminar model agreed better with the experimental results. Manoj |

Hi Satyanarayana
Try VOF (geometrical reconstruction), laminar, unsteady ( for both steady and unsteady state problems).. What error are you getting? You might be getting it because of wrong inputs. Regards, Manoj |

im getting the turbulence intensity is limited to 1*10^5 in sme cells for some iterations and then it is showing floating point error and then stopping,can u help me in this regard
