material properties input
 

hello friends

I'm confused about the properties of my phase change material, how to fix it in fluent in a right way.

Below is a photo of my PCM thermophysical properties which indicates that the solid and liquid phase has different thermophysical values.

So how i should input these values correctly.

I tried the polynomial option but the results diverges.

Any insight will give much help.

thanks in advance.Attachment 99183
