Macroscopic Modelling of Environmental Influence on Growth and Form of Sponges and Corals Using the Accretive Growth Model

Figure 4

Simulation box. In the advection-diffusion simulations it is assumed that the top plane is the source plane of nutrients, while the nutrients are absorbed at the surface of the simulated growth form. In the light simulations it is assumed that the light direction corresponds to the vertical and that all light is absorbed at the surface of the object.
