-The default non-electrostatic short-range potential is morse-stretch (ms), alternatively a Buckingham-potential +The Coulomb potential can be combined with any analytic (short-range) pair potential. Morse-Stretch (ms) and Buckingham (buck) potentials are adapted to use with Wolf-Summation for dipoles by assuring zero gradient at the cutoff. Coulomb potentials can be combined with [[interactions:eam_elstat|EAM]] or [[interactions:angular_coulomb_potentials|angular-dependent]] potentials by using the force calculation routines built for this purpose.
