The evolution of a particle under surface diffusion and migration

RESULTS

Using the Matlab code, the following simulations were performed. The start of the Matlab code asks the user for an input of the number of nodes desired for the simulation. Then, the user needs to input whether or not they want to draw their own arbitrary shape. If the user does not desire to draw the starting shape, the code will automatically start the simulation with a circular particle.

The final user input is the b value to determine the surface tension anisotropy. This needs to between 0 and 1. If something other than zero is desired, then another user input is available to choose, the k value of the equations. This determines the final shape of the particle.
