solidification in a square cavity
 
dear,
i have to simulate the solidification of water in square cavity by FLUENT... threee boundary are insulated (i put wall with nul heat flux as BC and it's not converge?????????) and one boundary is cooled unver the liquidus temperature of water..
i use a 2.5cm*2.5cm cavity, maillage 30*30, steady or unsteady solver, anD a polynomial development of the density in material panel..
if i try to iterate i havent a temperature gradient (the energy panel is activated)..and the liquid fraction still 1 in all the cavity.
can any one help me please????
thanks.

What re urs liquidus and solidus temperature?
