Hi
I want to use the "delete_atoms" command to remove a randomly selected fraction of atoms from a group (as opposed to a spatial region).
"delete_atoms porosity..." will delete a portion of atoms inside a specified volume (but not by group)
"delete_atoms group..." will delete all atoms of a specified type (but all atoms will be deleted, a fraction is no an option)
I only want to delete some atoms (not all) and by atoms type (not spatial coordinate). What are my options in LAMMPS?
Thanks,
Nicholas J. Lee
