cgwf3 warnings

Dear all, When doing response calculations (phonons, Born effective charge or else) these errors appears really often on a large number of iterations steps: cgwf3.F90:701:WARNING New trial energy at line 4 = -4.144536E+02 is higher than former: -4.144536E+02 I can have more than 1000 of them in my l...

7) I've also try with only one long SCF cycle:

Code: Select all

 scprqt:  WARNING -
  nstep=  500 was not enough SCF cycles to converge;
  density residual=  2.619E+03 exceeds tolvrs=  1.000E-12

Problem convergence SCF

Hi, I'm currently trying to calculate the optimal height of a fcc FeNi L10 ferromagnetic supercell containing 10 atoms (it is an hexagonal structure in the (111) plane). My SCF cycle does not converge: BROYDEN STEP NUMBER 0 ------------------------------------------------------ iter Etot(hartree) de...
