12.19.3 Vorticity- and Strain/Vorticity-Based Production

For the Spalart-Allmaras model, you can choose either Vorticity-Based Production or Strain/Vorticity-Based Production under Spalart-Allmaras Options in the Viscous Model panel. If you choose Vorticity-Based Production, FLUENT will use Equation  12.3-8 to compute the value of the deformation tensor $S$; if you choose Strain/Vorticity-Based Production, it will use Equation  12.3-10.

(These options will not appear unless you have activated the Spalart-Allmaras model.)
