uncle_salty is on a distinguished road
I'm trying to model a 2D natural convection problem that seems simple, but my solution won't converge.

i have a 2D square. left wall = hot ; right wall = cold ; top and bottom walls are adiabatic.

air is the fluid in the cavity and i have set its material properties as polynomial functions of temperature.

i want to show the natural circulation temperature profile, but i can't get my solution to converge.

can anyone help, please?
