tommy Guest Posts: n/a	I AM DOING SOME SIMULATION ABOUT STEADY LAMINAR NATURAL CONVECTION IN A SQUARE CAVITY AT VERY LOW PRANDTL NUMBER (LIQUID METALS), BUT I HAVE SEVERAL PROBLEM IN THE CONVERGENCE OF THE CALCULUS, ALSO FOR VERY RELAXED EQUATIONS (0.01) AND ALSO FOR MULTIGRID TECHNIQUES. THIS PROBLEMS ALSO REMAIN FOR THE TRANSIENT. THERE IS ANYONE WHO CAN TELL ME IF HE HAS THE SAME PROBLEMS? I NOW THINK THAT CFX IS NOT SUITABLE FOR THE CONVECTION OF LIQUID METALS!!
