Sounds like the simplest approach is to model the ice cream as a solid with a variable specific heat as a function of temperature, and include in it a jump which represents the latent heat of...

Are there any moulds, pipes, formers or anything else to hold things in place? I assume they are made of metal or plastic or something. Or is the liquid ice...

Then do a simple single phase model to just get the HTC and use that in an ODE approach. That may mean the ODE approach is intractable depending on the geometry and how the stuff melts. Can't...

You still have not explained why CFD is needed here, why won't a simple ODE solution be good enough? You would have the answer after a...
