Dear Vahid,
Could you share all your input and output files via Google Drive? I will have a closer look at this problem. Greetings, Iurii -- Dr. Iurii TIMROV Senior Research Scientist Theory and Simulation of Materials (THEOS) Swiss Federal Institute of Technology Lausanne (EPFL) CH-1015 Lausanne, Switzerland +41 21 69 34 881 http://people.epfl.ch/265334 ________________________________ From: users <[email protected]> on behalf of Vahid Askarpour <[email protected]> Sent: Tuesday, January 11, 2022 3:17:19 AM To: Quantum ESPRESSO users Forum Subject: [QE-users] Reconstruction problem in hp.x Dear QE Community, I am running Hubbard U on a relaxed slab of 96 atoms with a 25Angstrom vacuum. I generated all the response function matrices (using sum_pertq) but when using compute_hp to collect all the chi0 and chi matrices, I get the following error: Many lines similar to the ones below Missing chi element for: na= 288 nb= 89 dist= 21.669460 Missing chi element for: na= 288 nb= 91 dist= 19.080347 Missing chi element for: na= 288 nb= 161 dist= 7.914550 Missing chi element for: na= 288 nb= 163 dist= 18.450123 Missing chi element for: na= 288 nb= 233 dist= 12.788988 Missing chi element for: na= 288 nb= 235 dist= 7.619240 Possible solutions: 1. Relax better the structure (in order to have more accurate inter-atomic distances) 2. Increase the value of the parameter eps_dist in PW/src/ldaU.f90, then recompile the pw.x and hp.x codes, and re-run the HP postprocessing step by setting compute_hp=.true. in the HP input. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Error in routine reconstruct_full_chi (1): Reconstruction problem: some chi were not found %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% The structure is relaxed and the forces are quite small with zero stress on the cell. I increased eps_dist to 0.1 and still get the above error. Any suggestion as to how to avoid this error is deeply appreciated.
