| contents | We study the onset of bulk avalanches and boundary outflow in the Bak Tang Wiesenfeld (BTW) model and in the stochastic BTW models by computer simulation. We also study the dependency of these two onset times on system sizes. We observe that these two onset times follow simple power-law dependency on system sizes. We estimate these power-law exponents both for the BTW model and for the stochastic BTW models. We observe the evolution of the density of the system and estimate self-organized critical (SOC) state density both for BTW and stochastic BTW models. We study the boundary distribution for BTW and stochastic BTW models and show that boundary distribution does not follow a power-law distribution. In this paper, all the investigations are done for one-dimensional, two-dimensional, and three-dimensional cases. |
