Natural convection simulation

Please login with a confirmed email address before reporting spam

When natural convection simulations are performed, the expected results are obtained when the heat source boundary is set as a constant temperature boundary, while the simulations do not converge when the heat source boundary is set as a boundary heat source and a generalized heat source is used. What is the reason for this? If you guys have any idea, we can discuss together. Thank you very much!
