Software for spatially-explicit simulation of forest dynamics

Relationship of behaviors to trees and grids

Trees and grids are the state data of SORTIE. Behaviors act on this data to change it and evolve the model state.

Behaviors are assigned to specific data, and may not act outside this scope.

SORTIE directly manages all the state data needed for a given simulation and automatically ensures the creation of any data that a behavior is assigned to work on. Users can adjust the initial conditions of all state data at the beginning of the simulation.
