Fig 2. A polymer in the MEDYAN model.

Fig 2

A cylinder based scheme is used in the MEDYAN force fields to model semi-flexible polymers. Here, σ 0 is the diameter of the cylinder and l 0 is the equilibrium length, where l 0 > > σ 0. We assume that axial deformations of the cylinders are small and radial deformations are forbidden.
