Abstract：
A parallel self-consistent code SBBE to simulate the beam-beam effects in e+e- storage ring has been developed. It calculates the transverse kick in a collision by directly solving the Possion equation with an open boundary. Radiation damping effect and excitation random effect are included in arc transport. By using this code,the simulation of beam beam interaction on BEPC was made,and the simulated result was compared to the experiment result. The simulated luminosity agrees to the measured one qualitatively. The beam-beam limit was calculated in simulation and agreed well with the measured one.
