2d natural convection -- CFD Online Discussion Forums

uncle_salty New Member Join Date: Oct 2009 Posts: 6 Rep Power: 17	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?
