Numerical Modelling

Roesner Pty Ltd utilises a custom built software tool that comprises nearly 2000 lines of FORTRAN code to simulate the behaviour of the particles on the disc, impacting with the vanes and travelling radially outwards, after which traditional ballistic trajectories calculate the particle landing position relative to the centre of the spreader.

The Numerical Model can be used to create virtual spread pattern and to carry out sensitivity analyses to determine how parameters such as vane angles, spinner RPM and wind speed and direction affect spreading performance.
