problem with dump in loop

Hi Dear Axel
Thanks for your reply.

I have tried to make dump outside of loop, but it didn’t work or make error
reuse of dump id.
Actually, I want make oscillating field and then dump each 5 step among 100
loop, could you advise me how to make it?
Sincerely Yours,
Mahbub

Hi Dear Axel
Thanks for your reply.

error
  reuse of dump id.

if it doesn't work, you are doing it wrong and this error message is
pretty much self explanatory.

Actually, I want make oscillating field and then dump each 5 step among 100
loop, could you advise me how to make it?

the fix efield documentation gives an example (well, part of it, for
the rest you need to read the variable documentation), which doesn't
require a loop.

please note, that people on this mailing list don't have the time to
be somebody's personal tutor.
