The discussion centers on creating a body-centered cubic (BCC) lattice using Fortran code for simulation purposes. The original poster seeks guidance on writing 3D lattice coordinates, having previously implemented a simple cubic lattice but struggling with BCC. Participants suggest clarifying the simulation's focus, such as electronic transport or phonon propagation, to provide more tailored advice. Resources are shared, including links to projects on Tight Binding and Empirical Pseudopotential methods, which may offer relevant documentation and examples. Additionally, references to advanced methods like Augmented Plane Waves and Korringa–Kohn–Rostoker are mentioned, indicating that while they are more complex, they share similarities in lattice implementation.
