Dear experts,

I am once again confused.
Look at the two pictures:
Fluent 13.0
Fluent 14.5

It's a flow over a bluff body, flow enters on the left (velocity inlet) and leaves on the right (pressure outlet). Front and back are symmetry planes, top and bottom are periodic.
Pictures show iso surfaces of Turb. Kin. Energy. Both flows use the same grid, the same initialization, settings and so on. SAS turbulence model! (14.5 looks like URANS)
Did they change anything from 13.0 to 14.5 that could cause such a difference?
The skeleton ran out of shampoo in the shower.
