[lammps-users] Variable bin thickness for compute chunk/atom bin/1d command.

Dear LAMMPS users,

I am using LAMMPS version 8 Apr 2021. I have a test case of liquid gas vaporization and I am trying to evaluate the density and temperature distribution along x-direction (where the liquid-vapour interface lies) using ‘compute chunk/atom’ and ‘fix ave/chunk’. I want to vary the thickness (delta) of the bins in the ‘compute chunk/atom bin/1d’ command to have smaller bins in the liquid phase and larger bins in the gas phase. Is there a way to do it instead of using 2 different ‘compute chunk/atom’ commands for the liquid and gas phase? Please let me know.

Thanks

All available options for defining chunks are provided in the documentation of the compute chunk/atom command.
