FLOW™ ... applies wind pressure to 3-dimensional sail mold

Using Flow, wind pressure is introduced over the sail’s three-dimensional “mold” to produce a pressure field on the sail’s surface. The pressure varies over the surfaces based on the size and shape of the sail and the strength and direction of the air flow. The resulting pressure field is then linked directly to Membrain for finite element analysis. Flow also reports the drive and moments developed by sails, which can later be used by either the North Sails VPP or other VPPs for sail performance analysis.
