Do you need the time series or the final snapshot data? As of 20.4 release, you can save the particle coordinates at the end of a run into an ASCII file (see below). The file name is particle_output.dat and it has the same format as the particle_input.dat format. The idea is you can run a simulation, save the data and reuse it for another simulation (rename particle_output.dat to particle_input.dat). This option may be useful if you need to settle particles. There is another option to reset the velocity to zero.
