'''Fiber simulation''' is a branch of [[mechanics]] that deals with modeling the [[dynamics (mechanics)|dynamics]] and [[rheology]] of particles of large aspect ratio, or [[fibers]] with the goal of predicting the properties of fiber [[suspensions]] and networks based on [[first principles]]. Simulation of fiber suspensions have applications in paper industry and also in [[composites]], including composites made of [[carbon nanotubes]]. Many of the models used to simulate fibers were developed by researchers in the field of [[rheology]]. Rheologically speaking fiber suspensions are [[non-Newtonian fluid]]s, and can display [[normal stress]] differences.
Early fiber simulations employed particles which were rigid rods or prolate [[spheroids]], whose [[equation of motion|equations of motion]] have analytical solutions. More recent models are able to represent flexible fibers. The models rely heavily on [[continuum mechanics]] concepts and the numerical methods employed have some similarities to those employed in [[molecular dynamics]], or in dynamics of multi body systems.
The use of computers facilitates greatly the solution of fiber simulation problems. The complexity of the simulations arise from the system having a large number of [[degrees of freedom (physics and chemistry)|degrees of freedom]], and from the numerous possible interparticle interactions having place, such as [[friction]], hydrodynamic interactions, and other kinds of interparticle forces such as [[colloidal]] forces that exert attractive or repulsive forces.
