   provided by Martin Kroger (ETHZ).

+- validation_nve:
+  simulates a small assembly of magnetic atoms (54). The atoms are 
+  coupled by an exchange interaction and a mechanical potential 
+  (EAM here). 
+  This example represents an NVE run: the total energy of the 
+  system is preserved, whereas the spin and lattice energy 
+  reservoirs are exchanging energy.
+  Run as: ./run-test-nve.sh
+  Output: res_lammps.dat contains the data. The results are displayed
+  by nve_spin_lattice.pdf.
