This is a simple script to simulate the dissociation of a single +1 topologic defect into two +1/2 defects. The defects have like charges and thus repell each other. Since the free energy of a topologic defect is propto its topological strength k, the free energy of the system is reduced by half in the course of this process. The .zip folder contains a video of the animation (.gif, .mp4) in case you cannot execute the script yourself and the governing equations provided as a .pdf
