turbulent mixed convection
 
Hi, dear freids,; can any one help me. I'm working on the mixed convection with number of Grashof greater than 2.5e07. when I fixe the temperature on the wall to obtain gradient of temperature for calculation of the Gr desired, fluent limits the temperature 5e03. I don't understand how if I use g>9.81 or what? thank you
