Santa's Sleigh Upgraded with Computational Fluid Dynamics Simulation

Santa's sleigh CFD

Santa Claus’s new sleigh, designed with simulation, is more aerodynamic and built to handle supersonic speeds.

ANSYS celebrated the holiday season by attempting to improve the deer-energy efficiency of Santa Claus’s sleigh and thus protect the Christmas figure from the harsh elements. CFD simulation revealed that the drag on Santa’s traditional sleigh was very high. The newly designed sleigh, which resembles a small aircraft, reduces drag by 90 percent and now, hypothetically, can reach even supersonic speeds.
