For starting, I built a Nx = Ny = Nz = 2 supercell (the Ni and Ni3Al lattice parameters are very close), resulting a 32 atoms system. The input file is: &control calculation = 'vc-relax' restart_mode= 'from_scratch' prefix='NiNi3Al' tstress = .true. tprnfor = .true. pseudo_dir = '/home/martins/programas/espresso-4.2.1/pseudo/', outdir='/home/martins/calculos/QE/NiNi3Al/32at/' / &system ibrav = 1, celldm(1) = 13.45, nat = 32, ntyp = 2, ecutwfc = 50.0, nspin = 2, starting_magnetization(1) = 0.0, starting_magnetization(2) = 0.2, occupations = 'smearing', smearing = 'mv', degauss = 0.02, / &electrons diagonalization='david' mixing_mode = 'plain' mixing_beta = 0.7 conv_thr = 1.0d-6 / &ions ion_dynamics = 'bfgs' / &cell cell_dynamics = 'bfgs' cell_dofree = 'z' / ATOMIC_SPECIES Al 26.981 Al.pbe-sp-van.UPF Ni 58.693 Ni.pbe-nd-rrkjus.UPF ATOMIC_POSITIONS angstrom Ni 0.00000 0.00000 0.00000 Ni 0.00000 1.77936 1.77936 Ni 1.77936 1.77936 0.00000 Ni 1.77936 0.00000 1.77936 Ni 3.55872 0.00000 0.00000 Ni 3.55872 1.77936 1.77936 Ni 5.33807 1.77936 0.00000 Ni 5.33807 0.00000 1.77936 Ni 0.00000 3.55872 0.00000 Ni 0.00000 5.33807 1.77936 Ni 1.77936 5.33807 0.00000 Ni 1.77936 3.55872 1.77936 Ni 3.55872 3.55872 0.00000 Ni 3.55872 5.33807 1.77936 Ni 5.33807 5.33807 0.00000 Ni 5.33807 3.55872 1.77936 Al 0.00000 0.00000 3.55872 Ni 0.00000 1.77936 5.33807 Ni 1.77936 1.77936 3.55872 Ni 1.77936 0.00000 5.33807 Al 3.55872 0.00000 3.55872 Ni 3.55872 1.77936 5.33807 Ni 5.33807 1.77936 3.55872 Ni 5.33807 0.00000 5.33807 Al 0.00000 3.55872 3.55872 Ni 0.00000 5.33807 5.33807 Ni 1.77936 5.33807 3.55872 Ni 1.77936 3.55872 5.33807 Al 3.55872 3.55872 3.55872 Ni 3.55872 5.33807 5.33807 Ni 5.33807 5.33807 3.55872 Ni 5.33807 3.55872 5.33807 K_POINTS automatic 2 2 2 0 0 0 However, I've got the following error message: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% task # 0 from cdiaghg : error # 201 diagonalization (ZHEGV*) failed %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% I did some variations on the input parameters (CG instead of DAVID, DAMP instead of BFGS, ...) and the calculation continue to giving the same error message. Are there some problem with my input file? Any suggestion? I appreciate any help.
