Dear Lammps users,
I have a question regarding Delete_atoms command in LAMMPS and I appreciate any help in advance
Firstly, I create 2 atom types in LAMMPS by using create_atoms command，
And, I give two different mass to each atom type by using mass command,
Then, after I relax the system, I want to remove one type of atoms,
So, I use Delete_atoms command to delete the specified group atoms
$ delete_atoms group 2
(group 2 contain the whole 2nd type atoms).
At last, I use write_data to output the system data.
But, when I check the output data file,
It still contains 2 kinds of atom, and mass also has 2 kinds types.
But, the atoms were deleted by the delete_atoms command.
so is that any bug of LAMMPS,
or can I use any command remove the atom type and mass when I delete atoms?
