Hi ,how are you ?
actually im beginner in using ansys fluent i just read alot of tutorials and i have problem in doing simulation of my case its free convection laminar flow in cavity ...its a 2D ,rectangle ,inlet from bottom ,outlet from top ( the flow is up ward) the fluid is air , also the left and right as a wall have a constant temp ( have the same temperature ) between the two wall have a heat source reject the heat to the space between left and right wall by free convection ..the density should be change with temperature and should add a very small value for velocity as a trigger to start the solution .....does any one have a tutorial or advise to me on what should i set the boundary condition and the setting for the case to reach the solution ....
thank you so much
