Tin Melting Front
Model ID: 6234
This example demonstrates how to model phase transition by a moving boundary interface according to the Stefan problem. A square cavity containing both solid and liquid tin is submitted to a temperature difference between left and right boundaries. Fluid and solid parts are solved in separate domains sharing a moving melting front. The position of this boundary through time is calculated according to the Stefan energy balance condition. In the melt, motion generated by natural convection is expected due to the temperature gradient. This motion, in turn, influences the front displacement.
