Ciao Giuseppe, Yes there is a small program that does that : dynmat.x Call it like this: $espresso_dir/bin/dynmat.x
then feed this one line input (no need for a separate input file) &input fildyn='yourfile' / it produces dynmat.axsf where the normal modes are represented as forces in xcrysden, an animated xsf file, one frame per mode. xcrysden --axsf dynmat.axsf This is how it was working last time i checked, i dont think anything has changed.. emine kucukbenli, phd student, sissa, italy ps: after writing i remembered this: http://people.sissa.it/~degironc/QE-Tutorial/tutorial_phon.htm check the "Phonons at Gamma point" section - last bit. Quoting giuseppe.mattioli at mlib.ism.cnr.it: > Dear all > Does anybody know if there is any post-processing tool which allows > one to visualize normal modes calculated with phonon.x or phcg.x in > real space, as, for instance, ion displacement movies to be opened > with xcrysden or xmakemol? > Thank you in advance > > Giuseppe > > Giuseppe Mattioli > ISM-CNR > Italy > > > _______________________________________________ > Pw_forum mailing list > Pw_forum at pwscf.org > http://www.democritos.it/mailman/listinfo/pw_forum
