Reg: pair style lj/cut/coul/dsf - correction needed in manual ?

Hello lammps users,

I am trying to use Fenell summation for electrostatic interactions.
I am using the command as follows.

pair_style hybrid lj/cut/coul/dsf 0.1 10

So this doesn’t work. But the manual says

*lj/cut/coul/dsf* args = alpha cutoff (cutoff2)
  alpha = damping parameter (inverse distance units)
  cutoff = global cutoff for LJ (and Coulombic if only 1 arg) (distance units)
  cutoff2 = global cutoff for Coulombic (distance units)

However the following works

pair_style hybrid lj/cut/coul/dsf 0.1 10 10

In the code shouldn’t the following be set to 2 ?

if (narg != 3) error->all(FLERR,“Illegal pair_style command”);

Please check the above. If the mistake is on my part I will recheck again.

Thanks
Arun

yes, the code did not allow cutoff2 to be optional.

I updated the code to match the doc page - it will

be in the next patch …

Thanks,

Steve
