Steady state vs. transient while modelling solidification/melting in FLUENT
 

I'm selecting steady state for a melting problem right now, but once convergence is reached it shows the liquid fraction for the whole domain as 1. In this case I guess it is appropriate to solve a transient problem instead of steady state?

Any extra tips regarding the selection of steady state vs transient specifically for melting/solidification will be welcome.

Try to solve it with a transient state and compare both results. Also extract results at various time steps to see the changes in your desired output result.

Could you explain your problem setup more detailed? I can not imagine a steady case with a liquid fraction between 0 and 1, it will always 0 or 1. So it should be a transient problem.
