Complete cast

Purpose

The purpose of this section is to show results for a simulated complete cast starting with the line on the water surface and ending with the line having landed on the water. This demonstrates the possibility to simulate line interaction with a water surface.

Input, casting strokes

The complete cast includes hauling and feeding of line, starting at 60ft and ending at 72ft. It is shown as three simulations:

1. A pick-up stroke.

2. Two false strokes.

3. A delivery stroke.

The input boundary conditions for the false strokes and the delivery stroke are shown below:

Input, equipment

The equipment used is identical to the equipment used in the 50ft oh ref. cast.

Comments, animation:

The animation demonstrates the capability to simulate interaction of the line with a water surface. The axial drag on the fly line on the water surface produce what is referred to as an “anchoring effect”. In the vertical direction the buoyancy i.e., the force that makes a floating fly line float on the surface, gives the line a realistic landing on the water surface. It is noted that surface tension forces also contribute to the buoyancy of the line.

Output, graphs

The graphs considered most relevant are presented below for the false cast and the delivery. For explanations to the graphs please see the 50ft oh ref. cast.
