Description of the simulations :
Still under construction
1. Twisted vortex loop :


This shows a knotted vortex structure, more precisely a twisted vortex loop. Red and blue surfaces surround the core of the vortex in each component, while the conic arrows display the magnetic field.
1. Twisted vortex loop instability:


This shows a knotted vortex collapse. Red and blue surfaces surround the core of the vortex in each component,
