Transient and stationary behavior of the Olami-Feder-Christensen model.

Using long-term computer simulations and mean-field-like arguments, we investigate the transient time and the properties of the stationary state of the Olami-Feder-Christensen model as function of the coupling parameter alpha and the system size N. The most important findings are that the transient time increases with a nonuniversal exponent of the system size, and that the avalanche size distribution will not approach a power law with increasing system size.
