Question Selection of timestep and initialisation for melting/solidification problem

vsing is on a distinguished road
I am trying to simulate the (transient)melting of a PCM(solidus 302K, liquidus 305K). I wish to initialize each domain/cell zone(i.e, metal, ambient air, PCM zone, hot fluid etc.) separately, to different kinds of initial conditions. How do I proceed with doing that? Also, the minimum cell size in my case is 5e-04 m, what could be an appropriate time step size, I am using Implicit scheme, what should be my choice if I wish to minimize the numerical oscillation in my solution(i.e rapid solidification, and melting).
Thanks in advance!
