Building up a body centered cubic lattice

• Consider:

1. a cubic simulation box whose sides are of length $\left.L\right.$
2. a number of lattice positions, $\left.M\right.$ given by $\left.M=2m^{3}\right.$, with $m$ being a positive integer

• The $\left.M\right.$ positions are those given by:

$\left\{{\begin{array}{l}x_{a}=i_{a}\times (\delta l)\\y_{a}=j_{a}\times (\delta l)\\z_{a}=k_{a}\times (\delta l)\end{array}}\right\}$

where the indices of a given valid site $(i_{a},j_{a},k_{a})$ must fulfill:

• $i_{a},j_{a},k_{a}$ must be either all odd or all even.
• $0\leq i_{a}\leq 2m$
• $0\leq j_{a}\leq 2m$
• $0\leq k_{a}\leq 2m$
