Training to Empower Your Teams

Improve your Frisbee game with computational fluid dynamics!

People take sports seriously! Computational fluid dynamics (CFD) simulations have been used to increase the range of golf balls and improve the spiral of footballs. The dynamics of an ultimate (Frisbee) disc are complex, and ATA’s team of ultimate aficionados was interested to see whether we could accurately simulate the effects of off-axis spin on the disc’s flight characteristics.


In this webinar, we’ll discuss the history of Frisbee development, demonstrate how STAR-CCM+ can be used to model the aerodynamic forces for a Frisbee, and assess how CFD can be used to improve Frisbee design and player technique.



  • Introduction to relevant STAR-CCM+ features for this application, including mesh motion and Simcenter Cloud HPC
  • Review of STAR-CCM+ Frisbee model setup and results
  • Discussion of ideas for future work
