There must be someone who knows this kind of problem.
when i calculate the phonon band structures by using ph.ix, i confront with "
12 total processes killed (some possibly by mpirun during cleanup)"
the end of scf.out has got "convergence has been achieved in 14 iterations"
but the phonon calculation are wrong :
Check: negative core charge= -0.000002
