[lammps-users] Qustion on lammps atom variables

LAMMPS LAMMPS Mailing List Mirror

Dear LAMMPS developer,

I need to store initial atom positions and use them later.
I read the Manual. It occured to me that one cannot evaluate variables of per-atom type like one can do like below for scalar variables:

variable v equal vol
variable v0 equal $v

I appreciate your consideration in advance
Joseph
