Thanks Michael. It is helpful to me.

Hi, I am working on phonon and electron-phonon coupling calculation using DFPT on bcc metal. but I contiuously have phonon softening. I think it is due to that bcc phase is not a ground strucutre, but I am not sure. I also relaxed the structure to get local minimum, it did not work. Is there some way to indirectly describe phonon in finite temperature?? Thanks in advance! Woong Kee.

Thanks for response Markus!. Is it due to the electron degeneracy or other assumptions?...
