Numerical simulations of beam-beam effects in the electron-positron Phi-factory DAPhNE taking into account the measured cubic nonlinearities have shown that the nonlinearities have a strong impact on the collider luminosity performance. The numerical results explain many of experimental observations made during collisions in both single and multibunch regimes.
