Hello every body.
I would be thankful if you could help me.
I am trying to run Binflow ,However there are some errors :(LIGGGHTS (Version LIGGGHTS-PUBLIC 3.3.1, compiled 2016-01-14-14:02:34 by kloss, git commit 9b1fc57b77c483deaf2c0a6c69241c5d4f91e3c2 based on LAMMPS 23 Nov 2013)

Thank you so much Daniel .
I have modified the code but still there is an error.(ERROR: Unknown command: overlapcheck yes vel constant 0 0 -1 region factory ntry_mc 10000 (/build/liggghts-QCz4in/liggghts-3.3.1+repack1/src/input.cpp:256)

Similar to the other issue
Read https://www.cfdem.com/media/DEM/docu/Section_input_script.html#parsing-r... about the
&
symbol. There seem to be some more of those errors in the script you posted (if the formatting here does not differ from your actual input script).
