Hi
i have two data one for solid phase and the other for the liquid phase, for example there is a liquid density and a solid density, the same for the Specific heat capacity, and the Thermal conductivity.
but in fluent, I can enter the parameters of a single-phase.
please, what can i do

After enabling the "solidification/melting" model, you should define the material properties of both solid and liquid phases by the piecewise linear state of each property instead of the "constant" state.

In "create/edit Materials" section, there is a drop-down menu for each property. There are several options such as constant, piecewise-linear, piecewise-polynomial, etc.
