Abstract We first note that the improved Boussinesq equation has a multisymplectic structure. Based on it, a multisymplectic scheme is proposed. Dispersion relations analysis and linear stability analysis show that the proposed scheme has excellent properties. Numerical results confirm the excellent long-term behavior of the proposed scheme.
