The evolution of a particle under surface diffusion and migration

CONCLUSIONS

Using the finite element method and Euler approximation technique the evolution of a particle under surface diffusion and migration has been simulated. The simulation program accounted for the change in size of a particle of any arbitrary shape. Adjusting the parameters of the simulation (such as the b and k value) will determine the final shape of the particle before it shrinks. The simulation program also allows one to study varied materials because in our simulations, the mechanical properties have been normalized. As a result, changing the mechanical properties would tailor the simulation to the special material of interest. In addition, the length scale has been normalized as well, and hence allows one to study the evolution of particle of any size by adjusting the length scale value.
