[Pw_forum] Selecting vales for doing Electric field calcualtions

[Mohammed Ghadiyali]

Dear all,


I intend to do calculations on a bilayer system with perpendicular electric field applied to it, as per the documentation and few forum post I am required to do following modifications:

&CONTROL
  tefield               =       .true.,
  dipfield             =       .true.,
&SYSTEM
  emaxpos           =       0.5D0,
  eopreg              =       0.1D0,
  edir                    =       3, ! To set z direction
  eamp                 =       0.0105,

But I not sure as how to select the values of emaxpos and eopreg, can any one inform as how it is required to be set.
