Prerequisites:
  ASE (https://wiki.fysik.dtu.dk/ase/)
  LAMMPS 1Jul11 or later, with MEAM package

Setup:
1) Export LAMMPS_COMMAND variable, following
    https://wiki.fysik.dtu.dk/ase/ase/calculators/lammps.html
2) Overwrite two files in ASE:
    ase/calculators/lammps.py
    ase/lattice/surface.py
   by two files included here:
     ASE_modif/lammps.py
     ASE_modif/surface.py

Execution:
  Change directory to any example subdirectory and execute the "command.sh" script therein:
    cd elastic_const/examples/meam_alloy_jel/
    ./command.sh
  Expected results are in the results/ subdirectory. For the elastic constants, all are obtained by
    elastic_const/elast.py
  script.
