Dear Sayan Chaudhuri,

At least both the cut-off energies should be the same in both calculations. I did not check the inputs in more detail, for example if the k point sets are consistent. If yes, the total energy in the larger system should be very close to four times the total energy of the primitive cell.

    Greetings,

      Dear Sayan Chaudhuri,

        If you multiply the number of cells by four, shouldn't you also multiply
      'tot_magnetization' by four too?

            Hi all,

               I am calculating DOS structure for a heusler alloy Fe2TiSb. When 
I am not
            using a supercell I am
            getting the same result reported previously, but after using a 
supercell I am
            getting very different
            result.
             I am attaching the scf files and DOS output for both the cases. 
Please tell me
            what mistakes I am doing
            while considering the supercell. The one with _sup in the name, 
contains
            supercell.

            Thanking you in advance,
               Sayan Chaudhuri
