about the species transfer during solidification
 

The species transfer equation during solidification in the manual, which is equation (23.2-10), it contains Yi; Yi,liq; Yi,sol; which one is the unknown variable to be solved? I suppose Yi and Yi,sol are substituted by Yi,liq, then Yi,liq is solved by solving equation (23.2-10), then Yi and Yi,sol are calculated by the results of Yi,liq, is that right? Thank you.
