How to compute the forces on a sail

The following video shows how Stallion 3D computes the forces on a sail.  The forces are computed from an .stl file of the flying sail shape and the deck of the sailboat.  Grid generation is automatic and Stallion 3D solves the Reynolds Averaged Navier-Stokes (RANS) to accurately compute the forces and moments acting on the geometry.

Thanks for reading.


  1. Would be interesting to calculate how close to the wind it can sail .

  2. Hi Mihai, this is a good idea. Stallion 3D can be used to test various angles of the apparent wind so you can determine the value of drive force versus angle.
