Fiber simulation
Fiber simulation is a branch of
fibers, i.e. particles of large aspect ratio length to diameter. Fiber simulations are used to gain a better understanding of production processes including fibers (textile and paper industry[1]), biological systems[2] or computer graphics.[3]
Modeling fibers
Many of the models used to simulate fibers were developed by researchers in the field of
normal stress
differences.
Simulation techniques
Early fiber simulations employed particles which were rigid rods or prolate
equations of motion have analytical solutions. More recent models are able to represent flexible fibers. The models rely heavily on continuum mechanics concepts[4] 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
colloidal
forces that exert attractive or repulsive forces.
