Hi, I've tested buoyantFoam to 0g in cases of water and air, only to investigate conduction effects in a cylinder heated in the walls and with adiabatic top and bottom surfaces. In the two cases my analytic solution (a transient analysis) was much different of the OpenFoam solution to the time for complete uniformization of the temperatures.

For air the error is 27% and for water 300%

I'm using the kinematic velocity, deltaH=0 and nmols=1. Is it ok?

Thanks!
