[lammps-users] WARNING: Mixing forced for lj coefficients

Dear all,

I 've used kspace_style Ewald/n with pair_style lj_coul for long-ranged interactions and when my simulation starts, I get this message: WARNING: Mixing forced for lj coefficients. What does it means? I don’t find any explanation at the site of LAMMPS or in the manual.

Yours faithfully,

Giannis
