I am running the following loop to input and extract heat from the
system, but I am getting illegal group command.
variable enrgy loop 1000
group qout region outcyl
fix 420 qout heat 1 -5.0e-8
fix 421 qin heat 1 5.0e-8
fix 422 all nve
group qout delete
jump in.lammps myloop
I encounter "Illegal Group Command" when lammps execute " group
qout delete" command. I just want to delete this group and recreate
one, so that the atoms which are not part of the region after nve run,
are not included in the qout group.
