Default Boundary condition for heated cavity
Posts: n/a
Hello all, I want to know how to specify the boundry condition for a heated cavity in GAMBIT? (my problem is that, when I assign "symmetry" for temperature of the insulated wall, velocities are also take this condition, however they should be set to zero ...) Thanx.

(reference benchmark problem : G. de Vahl Davis, "Natural Convection of Air in a Square Cavity: A Bench Mark Numerical Solution", Int. J. Numer. Meth. Fluids, vol. 3, pp. 249-264, 1983.)
