FIGURE 4.

A schematic illustration of the relation between a model’s accuracy and its capacity of reproducing long time-scale phenomena. In principle, an extremely accurate model might reproduce all phenomena that take place at a characteristic length and time scale that lies above that of its fundamental constituents; however, practical limitations make its usage impossible beyond a certain limit. The coarser the model, the longer the time scale that can be achieved, at the expenses of a shorter and shorter list of processes that it can manage to produce.
