Hi All,

I am simulating simple natural convection. After solving i can see a temperature distribution that suggests natural convection has worked. However, there are no velocity vectors but there are path lines that follow where I would expect them to go.

My question is: Does this mean I have movement of water particles in my model or are pathlines just and indication of where a particle would move IF it was released from that point.

Thanks, Dave

Hi Dave, I did the modelling of natural conveciton before. Yes, it is definately you should get the x, y, z velocity distribution of the continuous flow. Check the gravity and outside temperater. By the way, I searched your former poster about the two-phase flow. You are using Discrete phase model? Would you please check my poster of questions about discrete phase model? Thank you very much for your consideration. Good luck. Lisa
