<div dir="ltr">Dear all, <div><br><div><div>I'm confused by how the phonon code deals with el-ph and phonon dispersion on Hexagonal lattice. Let me clarify the problem: I have tested el-ph for a few systems(Hexagonal crystal systems like Silicene,Bi2Se3 and a cubic system) using Grid method by setting start_q and last_q, which is well demonstrated in example #2 in GRID_example. For cubic system, the el-ph work finished normally and I got the <font color="#ff0000">$prefix.dynq$q</font> (q from 1 to 4)files in my working directory, but for the
Hexagonal ones, ph.x failed to create these files, instead, every time I got files named <font color="#000000">$prefix.dynq$q.</font><font color="#ff0000">xml</font><font color="#000000">(I tested the npool from none to 4 and versions form 4.3.2 to 5.0.2)</font> . </div>
