Integrating High Performance Parallel Computing (HPC) with state-of-the art Computational Fluid Dynamics (CFD) and Structural Mechanics (FEA) software from industry leader ANSYS Doyle Sailmakers has recently begun utilizing a high resolution, fully coupled computational simulation environment designed specifically to answer real world sailing challenges.
The complex turbulent flow around sails, rigs, and hulls is calculated to solve for millions of data points in the flow surrounding the sails. The detailed stress distribution and deformation that results in the sails and rigs from the forces imposed by the flow is then calculated using a Structural Solver with a composites pre-processor to accurately model the complex overlapping fiber and panel layouts in modern sails.
As Jud Smith says: “I love the flow graphics, I don’t understand the process, but the results in improved sail performance are undeniable.”
