Hull Data one of the most powerful free surface Hydro CFD programs in the world. Hull Data is a Potential Flow, Free Surface Code used for sail and rig develeopent for America’s Cup teams, TP52s and Volvo Ocean Racers. The results from Hull Data are used to generate hydro resistance files for the North Sails VPP.
Shown ABOVE and BELOW is a hull being run through a series of heel angles to produce a matrix of hull drag to be used in the VPP. In this example, Hull Data is testing a hull at a speed of 5.5 meters/sec., a heel angle of 25 degrees and a yaw angle of 2 degrees.
