CRYSTAL_COORDINATES is a FORTRAN90 program, using double precision arithmetic, which generates the coordinates of a set of 4* NX* NY* NZ points in a rectangular block of NX* NY* NZ cells, with face-centered cubic symmetry.
The user is allowed to specify the width of a cell, and the maximum magnitude of a random displacement of each point.
The coordinate data is written to a file that can be used for visualization, or more likely as the initial condition for the coordinates of molecules in a molecular dynamics simulation.
