Abstract
Solutions of a non-linear Klein-Gordon equation are studied numericall y using a cubic B-spline finite-element method. Test results indicate that, when solitary waves interact, the final state obtained depends o n their relative velocity. The simulations confirm existing observatio ns and produce new results. The numerical algorithm developed is effic ient with an undemanding stability criterion.
