gravity

I want to incorporate the effect of gravity in my model. In my model I made one of the face to be 600 K as compared to other at 300 K. I was hoping to see natural convection effects around the hot face. I turned the gravity ON and specified Z direction acceleration due to gravity to be -9.81 m/s^2. But I am not seeing any movement around the hot face. What am I doing wrong ?

just a question, what are your material settings?

Probably you have to set the operating density.
