partition coefficient in Solidification and melting model with species transport

[z5132453]

Hi all, 

I am simulating alloy remelting process with alloy element evaporation. I would like to use solidification and melting model to describe the mushy zone. I define alloy as solvent and another alloy element as solute as a mixutre with using the species model. then I have following questions :

1. where to set up the partition coefficient Ki, I cannot find it in GUI?
2. where to set up the Eutectic mass fraction for each of component? i cannot find it in either materials for each fluid or for mixture.
3. if my alloy does not have a specific eutectic temperature, can the solidus temperature of solvent be appromatiely used as eutectic temperture?

any answer will be great help.

Thanks in advance!
