String Network Formation
Plaquettes of Cubic Space Lattice:
- Circle in field space fully covered as we span square of real space plaquette. String goes through plaquette.
- Circle in field space not fully covered as we span square of real space plaquette. String does not go through plaquette.
- Join strings through plaquettes to create string network. .
Assign a random field direction (0, 1 or 2) at each vertex of the cubic lattice
