A massive black hole (MBH) located at the galactic center is one of the critical components of its host galaxy. Therefore, understanding the formation and evolution of MBH is one of the pillars of understanding galaxy evolution. In the most numerical simulation, MBH grows by accreting gas. However, MBH might also grow by taking the mass of stars, especially at its early growth stage. We present tidal disruption accretion (TDA) as a possible channel of MBH growth. We also implement the TDA model in an AMR simulation code ENZO. Although it is far from complete, we could demonstrate that the TDA model should be important in understanding the early evolution of MBH and the galactic center.
