Symplectic method is applied to solve numerically ID time-dependent Gross-Pitaevskii equation. " Breathing" of the condensate is numerically illustrated. Interaction of two Bose-Einstein condensates is investigated as external potential is zero at t = 0. Interference between two condensates is observed. Evolution of density due to interference at various relative phases is studied.
