Dear all,

I'm currently attempting to build a model similar to the "Tin Melting Front" in the model library. This model describes the melting of a metal through the Stefan problem and models the movement of the melting front using the Deformed Geometry interface. In my particular problem I wish to model this melting front but also the movement of the free surface of the liquid metal (this is a similar problem to metal welding).

It is my understanding that the solid/liquid front should be modeled with the Deformed Geometry interface, but the movement of the free surface of liquids is modeled with the Moving Mesh interface.

Is it possible to use both interfaces in the same model to describe the two different interfaces or is there another way to do this?

Thanks for the help.
Helena

Hello,

i think that everything can be resolved by deformed geometry,
I am also interested in this kind of problem. It seems difficult to model, particularly conditions on the free surface where forces are equilibrate: superficial tension, gravity, magnetic pressure (for my case)...

Any ideas?
