1. open a 2D case file
note: check Define/Models/Viscous to verify that LES is not present for a 2D problem

2. type (rpsetvar 'les-2d? #t) and press enter
note: you have to include the parentheses

3. go to: Define/Models/Viscous and you'll see that the LES model has been enabled for the 2D case.

turbulence is a 3D phenomenon and so, by using it to model a 2D problem your results may lose some of their predictive capabilities.
