pair_coeff NONE

Hello,

I’d like to set no interactions between atom types 1 and 2.
When I do “pair_coeff 1 2 none”, error message “Incorrect args for pair coefficients” shows up although “none” is default in the documentation page.

Even if I do like :
“pair_coeff 1 1 1.0 1.0
pair_coeff 2 2 1.0 1.0”
error message " All pair coeffs are not set" pops up.

Would anyone let me know how to set NO pair interactions?

Thank you.

just assign standard parameters and use

neigh_modify exclude type 1 2

instead.
