These models have several disadvantages. For example, disk interactions are typically a function of particle overlap, yet the model assumes that the disks remain circular during overlap. The shapes of the cells can vary in the vertex model, however, the packing fraction is fixed at $\\phi=1$. Here, we describe the deformable particle model (DPM), where each particle is a polygon composed of a large number of vertices.
