[mayank gupta]

Thanks Dr Merlin for your guidance. one more thing i want to ask you
that How much I should increase FFT mesh, default value is (120 120
120) and in output file I am getting the warning like
  negative rho (up, down):  0.691E+00 0.000E+00


 I have chosen 10 times ecutrho that of ecut.




Thanks
