[Pw_forum] QHA calculated error !
Hi,Paolo I get it. I change the phdos.in 0.75 Zn O to 0.75 Zn Zn O O. But the phdos.in of AlAs of example is Al As, and is not Al Al As As. Why? Could be anyone known?

Both terminal entering step by step and script can not be work when using 'phonon_dos.x <frequency'.And the fc file is not wrong,the dispersion cure can be obtained. So anyone could help me ?

[Pw_forum] Interatomic force constant
Dear Mr. Onaiwu, Quantum ESPRESSO can calculate IFCs from first principles, and then it has small utilities for calculating phonon dispersions from the calculated IFCs. Of course, it does not make any sense to sense to "change" the IFCs calculated from first principles, because the ICFs are the *output*, not the input, of the calculations. Once the IFCs are calculated and stored, as said, they can be used to calculated vibrational dispersions. Nothing forbids to change the calculated IFCs for further reuse, provided one knows what one is doing, and why. This being said, it seems to me that the pw forum would be the ideal arena for discussions such as the present one. For that reason, I am forwarding my reply to your enquiry to the forum as well.

[Pw_forum] local density of states on parallel planes
Dear All, Hi. I was wondering if QE has a built-in function for calculating local density of states on planes. I need to get the LDOS on different planes parallel to one another. I tried to use ILDOS in post processing. However, I am not sure how possibly I can use the code to get LDOS on different parallel planes. I appreciate your help.

[Pw_forum] problems with vc-relax
Is it good enough to relax an arbitrary system with only gamma k-points? I thought it is necessary to do some test with k-points as this effect change from system to system. In my experience, more k-points is necessary for a metal-like system, i.e. graphene.

Hi, You are right. Tests should be done. I was suggesting "start" from gamma k-points to make a quick relaxation. After this, relaxation with larger k-points could be followed if necessary.
