Looking into using an adaptive timestep all seems sensible - however in terms of output is there a way to specify dumps at certain time intervals?
A lot of imaging tools out there assume a constant timestep, so to get a consistent time picture is the best way to modify the dump or is there an easier way?
Thanks,
Anthony
Anthony,
Particle dumps occur at timestep intervals rather than time intervals
(see: http://lammps.sandia.gov/doc/dump.html ). So the short answer is
no.
Getting dumps to occur at precisely the time-planes you want would be
very difficult since those time-planes would almost never line up
precisely with the end of timesteps. My recommendation would be to do
frequent dumps and then select those that are nearest your time-planes
of interest. This process could be refined and automated via changes
to LAMMPS, but LAMMPS doesn't currently have this feature.
