in one of the next versions we will provide a new solute redistribution stategy.
In linear phase diagram descriptions as well as in the extrapolation from quasi-equilibria using TC-coupling the redistribution condition will be dG(alpha)=dG(beta) instead of dT(alpha)=dT(beta). This will improve situations where phases with low miscibility are interacting like the solid phases in eutectic solidification.
Miscibility gaps like in spinodal decompostion still cannot be simulated, instead two distict phases have to be used.
