Abstract
The development of finite element modeling for simulating interface motion is described focusing on two mass transport mechanisms, the interface migration and the surface diffusion. The classical theory for interface migration is expressed into a weak statement, in which the normal velocity and any arbitrary virtual motion of the interface relate the free energy change associated with the virtual motion. An example with two degrees of freedom shows how the statement works. The weak statement connects the velocity components at all the nodes to the generalized forces.
