This model shows how it is possible with Simile to disaggregate a land area into a grid of hexagons instead of the squares normally used, and display results using a polygon diagram. Hexagons have many advantages, including being better able to model lateral diffusion because all the neighbours of a cell are at the same proximity. This model has an inter-cell flow in one direction only, representing the movement of biomass in a situation where seed dispersal happens only in one direction.
