<div dir="ltr"><div dir="ltr">Dear Developers and Users,<br><br>I am writing to echo the same problem that Zhouchao is facing.<br>I
am trying to calculate the phonon dispersion of TMDs (a two-dimensional
material) using a gamma-centered k mesh of 13*13*3. However, I get the
weightage error (just like Zhouchao) while using q points of 2*2*1,
3*3*1, and 4*4*1. I have previously edited the wsweight.f90 (following
Prof. Paolo Giannozzi advice in this forum). I have gone through the
entire mailing list and found out that a lot of users have faced the
same problem. So, I'd like to ask for your help. </div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, May 16, 2023 at 7:19 PM zhouchao via users <<a href="mailto:users@lists.quantum-espresso.org">users@lists.quantum-espresso.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div><p style="font-family:Cairo,sans-serif;margin:0px;color:rgb(36,41,47);background-color:rgb(234,236,240)">Dear Developer,</p><p style="font-family:Cairo,sans-serif;margin:0px;color:rgb(36,41,47);background-color:rgb(234,236,240)">I have calculated the phonon spectrum of a 2D material using a K-point of 20201 and q-point of 4 4 1.
