Vorticity- and Strain/Vorticity-Based Production for SA model

Hi,

When shall I use Strain/Vorticity-Based Production rather than the default Vorticity-Based Production for SA model?

Hi Anna,
Its basically a change in the equation, for vorticity based, the deformation tensor is solved using an equation based on rate of rotation tensor, while for strain/vorticity based, the deformation tensor equation involves both vorticity and strain tensors.

for additional information (to view the equations) you can follow this link:
