It can be used for +cases that cannot be handled in :doc:`special_bonds `, such as +1-5 interactions or hyrbrid simulations that require the use of different +weighting factors for different molecules. + +The following coefficients must be defined for each bond type via the +:doc:`bond_coeff ` command as in the example above, or in +the data file or restart files read by the :doc:`read_data ` +or :doc:`read_restart ` commands: + +* `w_lj` weight (0.0 to 1.0) on pairwise Lennard-Jones interactions + +* `w_coul` weight (0.0 to 1.0) on pairwise Coulombic interactions + +This command will typically be used in conjunction with + +---------- + + + +Restrictions +"""""""""""" + +This bond style can only be used if LAMMPS was built with the +USER-MISC package.
