Equations in documentation for "lj/mdf" do not display

Dear LAMMPS developers,

The equations in the documentation for the command “lj/mdf” (http://lammps.sandia.gov/doc/pair_mdf.html) are not displaying. Could you please fix this problem?

Thanks,
Jibao

oops - looks like we don’t have them - will have to contact the developer

who sent us the code …

Steve

Dear Steve,

Thank you. Could you please contact them and update the equations? I appreciate your time and help!

Thanks,
Jibao

Dear Steve,

Another question related to the cutoff in LAMMPS: At the cutoff, are the LJ and Coulomb potential by default shifted to zero by subtracting the value at the cut-off to ensure that the energy is the integral of the force?

Thanks,
Jibao

done

Steve

See the pair_modify shift keyword. It shifts the LJ energy. No shifts

are applied to Coulombic. Shifts do not affect dynamics.

Steve

Thank you so much!
