Hi,
The crystal structures created by the Crystal Viewer Tool have a dimensionless lattice constant, so the distance between atoms is completely defined by the input field “Size of sides of the unitcell”. So, for example, the distance between atoms in the default BCC simulation is 1.
In an actual material system, the lattice constant a has a definite value. Iron, for instance, has a bcc crystal structure with a = 0.28665 nm.
