Where is density change due to solidification/melting covered in the Bousinesq maths? 

If you're comparing a specific location, are you seeing instant melting at that point or are conduction/convection effects in either Fluent or the experiment likely to create differences in the result.  I tend not to assume either experiment or CFD results are wrong, however I regularly see that there are differences in what is modelled that explain why the results don't match.
