<div dir="ltr">Dear users,<div>I am facing issues in running NSCF and PDOS calculations using Q.E.6.6/6.5. I am getting a segmentation fault in the error file. I am trying to do a PDOS calculation for a large system (44 atoms) with a vacuum (12 ang.) and Hubbard U value. SCF is running fine but then I am getting the following error during NSF and PDOS (even the same k-points in NSCF as SCF giving the same error). I would be grateful for your help on this matter. I have checked other systems that are working fine with 6.6/6.5 so please give me some hints for this system-related problem.</div><div><br></div><div><br></div><div><br>   Program PROJWFC v.6.6 starts on  4Jan2022 at 13:15:52<br><br>   This program is part of the open-source Quantum ESPRESSO suite<br>   for quantum simulation of materials; please cite<br>     "P.
