FENE

From Wikipedia, the free encyclopedia

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

$F_i=\frac{H R_i}{1-(R/L_{max})^2}$
