Producing a POSCAR file. For the sake of example, let us create a unit cell of fcc aluminium, and write it in a POSCAR file: atomsk --create fcc 4.046 Al POSCAR. Alternatively you can just write "vasp" as output format, and Atomsk will know what it means: atomsk --create fcc 4.046 Al vasp. In both cases, Atomsk will produce a POSCAR file ...

WebAug 10, 2011 · 165. Here's the answer I found: Just to make the definition complete, in the Cartesian coordinate system: the x-axis goes through long,lat (0,0), so longitude 0 meets the equator; the y-axis goes through (0,90); and the z-axis goes through the poles. The conversion is: x = R * cos (lat) * cos (lon) y = R * cos (lat) * sin (lon) z = R *sin (lat ... Webx, y - coordinates in two-dimensional cartesian system.
