Can we use dimensionless formulation of the governing equations in Fluent?
For incompressible flows you can, by assuming density to be one and setting viscosity to 1/Re.

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...
