Dear experts and users,

I know that there is a possibility to restart the q-mesh interpolation, and it has something to do with the flags:
restart and restart_step
As I understand that, during the first run a file (or files) print XXX.sigma_restart1 should be created at checkpoints specified by restart_step.
My problem is that such files are never created. How to make the code create them?

Example of my input:

Code: Select all

 !To create q interpolatiom restarting points
  restart = .true.
  restart_freq = 10

  ep_coupling = .true.
  elph        = .true.
  kmaps       = .false.
  epbwrite    = .true.
  epbread     = .false.
  epwwrite    = .true.
  epwread     = .false.

Thanks in advance.
Best, Mikhail

Dear Mikhail,

It depend on the version of the code you are using. Note that the restart_freq has been renamed into restart_step now.

On the most recent version of the code, I think the XX.sigma_restart are not used anymore.
Instead it uses the restart_ibte.fmt file (will be renamed soon into restart.fmt).

In principle if you put the flag

Code: Select all

  restart      = .true.
  restart_step = 50

everything should be done automatically.
You can just restart in the same folder and it should work.

Best,
Samuel
