How could these structures be represented in an array or vector while still maintaining the lengths between atoms in C++?
I would like to construct a three dimensional vector to represent the configuration of:
An FCC Lattice.
A BCC Lattice
A HCP Lattice.
A standard three dimensional vector is essentially a SC Lattice:
The above are depictions of unit cells, the full lattices look like:
And for HCP:
The reasons behind it is to more accurately represent the crystal structure of a material using an Ising Model. I would like the lattice to preserve lengths in order to give an accurate calculation of the exchange constant.
