Hi,

May I ask could CFX-post output turbulence intensity directly?(I didn't find that output variable option.) Or I have to compute it manually by myself?

Thank you.

siw will become famous soon enough
I have not found it there myself so I made an expression using the turbulent kinetic energy and the mean velocity, see the wiki page for the equations:

I believe that "mean velocity" should be the local mean velocity, or just the local velocity for steady state, not the global mean velocity.
