Define a groupbased on particle diameter

Submitted by shao_lee on Tue, 08/13/2013 - 17:58

Hello everyone,

Could anyone be kind to tell me how to define a group based on particle diameter? Say, "group sub diameter <= A".

In the newest version of LAMMPS, this could be done by using 'variable' keyword with group command, as described in http://lammps.sandia.gov/doc/group.html

However, in the current version of LIGGGHTS (2.3.6), the 'variable' keyword cannot be used with group command.

Thank you in advance!

Hi Lei,

we're planning a merge for autumn - it will be in LIGGGHTS then.
Until then, you can try to merge on your own if you kno wwhat you are doing :-)

Cheers
