WebMay 21, 2011 · In phonopy, Sum rule is imposed just summing force constants on atom indices along Cartesian axes and subtract the sums divided by number of atoms. However this breaks another symmetry of force constants. FC_SYMMETRY imposes acoustic sum rule and force constant symmetry of exchanging a couple of atom indices repeatedly. http://phonopy.github.io/phonopy/
