Geometrical models are simple caricatures that are used to capture the essential features of a complex dynamics. For instance in dendritic growth the motion of a liquid-solid interface is determined by a free-boundary problem for a diffusion field (temperature, concentration of an impurity). This kind of problem is difficult to solve since it involves nonlinear integral equations.
