[lammps-users] How to dump initial atom positions in each timestep

Dear LAMMPS community,

is there an easy trick how to dump the initial atom positions in each
timestep? Up to now I process the dump with a script in order to swap
the initial positions with the actual positions after the run is
finished.

With kind regards,
Thomas Wagner.

why would you need to do something like that?
this will blow up your storage use needlessly
and i cannot imagine any use for the initial coordinate
positions that could not be done in a more efficient manner.

Dumps are done at the very end of a timestep. The
positions at the end of step N are the initial positions
for step N+1. How is that different than what you are
asking?
