    A typical QE workflow relies on three distinct components: Quantum Espresso Course For Solid-state Physics Pdf

    | Error message | Likely cause | Fix | |---|---|---| | Error in routine diagonalization (1) | Insufficient memory | Reduce nbnd, lower ecutwfc | | SCF convergence not achieved | Bad starting guess or mixing | Increase mixing_beta, try diagonalization = 'cg' | | ibrav not set correctly | Wrong lattice type | Check QE ibrav table (0 = free cell) | | No pseudopotential found | Wrong path | Set pseudo_dir correctly | Chapter 8: Density Functional Perturbation Theory (DFPT)
