SOD (Site Occupancy Disorder) program
SOD is a package of programs and tools for modelling site-disordered solids. It works in connection with codes like GULP and VASP for the simulations of systems with periodic boundary conditions.
SOD first reduces the number of site-occupancy configurations by taking advantage of the crystal symmetry of the lattice. It then creates input files for running GULP, VASP, etc to evaluate the configuration energies. Finally there is a program that takes the results from these calculations and obtain thermodynamic quantities using Boltzmann's statistics.
Two configurations are equivalent if they are related by a symmetry operation:
More information about SOD and the methodology involved can be found in the paper:
and in the papers listed below. The program was written in the Fortran90 language by Ricardo Grau-Crespo (University of Reading) and Said Hamad (Universidad Pablo de Olavide in Seville, Spain).
