This web site is dedicated to fly casting
simulations and intended for people interested in the mechanics of fly casting.
It is created by me, Hans Ekander, Åhus, Sweden. Fly fishing and simulating
reality are two of my passions that are merging together here.
Laguna Willmanco near Esquel in Patagonia has
given unforgettable fly fishing memories and therefore
given name to my company, Willmanco AB, and to this website.
The simulation model has been developed by me
for over a decade and rests on well proven methods and extensive verification.
Some features of this simulation model that are not (or only partly) found in
other fly-casting simulation models, see References, are listed below:
· Hauling and feeding of line. This feature makes it possible to
vary the line length as is done in practical fly fishing as well as in
competitive casting.
· Interaction with a water surface. This feature makes it possible
to simulate roll casts and complete casts starting with the line on the water
surface and ending with the line having landed on the water.
· Material damping. This feature increases modelling accuracy of
the fly rod and models viscous behavior observed in fly lines.
· Reynolds number dependent air drag.
This feature increases accuracy of air drag simulation especially for small
diameters and low relative velocities between air and line/rod.

he got me infected with his enthusiasm for fly-fishing. We share great memories
from fly fishing in some truly beautiful corners of the world.

Casting Instructor has generously shared his extensive casting experience and
sharp eyes helping in the developments towards simulating more realistic casts.

shared experimental data from measured casts and supplied ideas for
improvements contributing to the development of the simulation model.
