    This video is so nice. I have subscribed your channel. Will share these videos for sure.
    May I know which smearing (fermi-Dirac or mv) is good for semiconductors like BaTiO3 calculations.

      Again depends upon the materials, do some literature survey and find out the best for metallic, non metallic , semiconducting systems.

    got idea about cards and flags.but in celldm(1)=.................do. why do?what is this?

      Not do its d0 (zero) indivates power , like 3.0d0=3.0 !

    How did you incorporate the "GGA-PBE" Exchange correlation in your input file?
    I can see "input_dft='pbe'" ---> Does this mean "GGA-PBE" exchange correlation is incorporated?

    • @matsci-etalks5994
      @matsci-etalks5994  3 роки тому

      You have to set input dft to pbe and also choose the correct pp for use with the input dft specified.

    Sir for ibrav=0 , how to set CELL_PARAMETERS{alat}

      Read the manual for more details. Also you can try using PWGui for ease of setting these and etc.

    Sir how to choose k- points

      Rule of thumb is for bulk its nxnxn for 2d nxnx1 for 1d (c axis oriented say) 1x1xn
