“…Simulations can be brought into better agreement with experiments bymultiplying 6 -+. 7 by 1/3, which is a typical correction for the "Stobbs factor" between electron microscopy simulations and experiments 12,13,16 . 1:(7) calculations are independent, so they are evenly distributed over the number of available cores.…”

FEMSIM, a Fortran code, has been developed to simulate the fluctuation electron microscopy signal, the variance, V(k), from a model atomic structure. FEMSIM has been incorporated into a hybrid-reverse Monte Carlo code that combines an embedded atom or Finnis-Sinclair potential with the deviation between simulated and experimental V(k) data to refine an atomic model with structure constrained by both the potential and experimental data. The resulting models have experimentally-derived medium-range order.
