- SCF convergence tips
- Errors
- pw.x: error while loading shared libraries: libmkl_scalapack_lp64.so.1: cannot open shared object file: No such file or directory
- Error in routine bands (1): The bands code with constrained magnetization has not been tested
- Error in routine c_bands (1): too many bands are not converged
- Error in routine offset_atom_wfc (1): Mismatch between the requested and available manifolds
- Error in routine projwave (1): Cannot project on zero atomic wavefunctions!
- Error in routine set_occupations (1): smearing requires a vaklue for gaussian broadening (degauss)
- Error in routine setup (1): forces for hybrid functionals + US/PAW not implemented
- Error in routine sym_rho_init_shell (2): lone vector
- Error in routine system_checkin (12): ntyp too large, increase NSX
- ERROR: ‘EngineRestart’ option to restart a calculation from a previous wave function requires the .save directory
- I get a different error
