Hi everybody

I'm a CFX biginner. So i'm defining the boundary conditions for a new Simulation. I chose "buoyant", and entered the Gravity values for the three axes, and now I want to define the buoancy reference density, but i can only enter the reference tempreture. I only have the value of the reference density. How can i Change it??

Thank you

You can't change it. Buoyancy is a function of temperature in heat transfer systems.

Set the reference temperature to an rough average of the temperature you expect in your system.
