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.
