Hi friends,

I am analyzing the natural convection inside a liquid pool which has heat generation using FLUENT. I have tried with both surface heat flux option and volumetric heat generation rate option. In both the cases i am getting very large range of temperatures including negative values. Can anyone suggest some possible causes of this? Also if any specific care is required during natural convection with heat generation please give some idea.

Another problem associated with the analysis is that whenever steady state analysis is performed, it gives divergence. So i am forced to go for unsteady analysis only. Is it the peculiarity of natural convection problems or is there a way out?
