FENE

FENE stands for the finitely extensible nonlinear elastic model of a long-chained polymer. It simplifies the chain of monomers by connecting a sequence of beads with nonlinear springs. The spring force law is governed by inverse Langevin function or approximated by the Warner's relationship

This article is about finitely extensible nonlinear elastic. For other uses, see Fene.
An example of multi-bead FENE model

Where 'R_i = |\textbf{R}_i|' and H is the spring constant.

Total stretching force on ith bead can be written as: \textbf{F}_i - \textbf{F}_{i-1}.
