Normalized Helicity
How can I normalized helicity in cfx-post. I just used
velocity.Absolute helicity/(abs(velocity)*abs(vorticity))

but still got the [m^-1] unit. Am I missing something?

normalized helicity is defined as (Velocity dot Helcity)/(Magnitude (Velocity) * Magnitude (Vorticity)
CFX does not calculate dot product directly, you need to create manually, i.e. create an expression in CFX post and then create a variable and select the expression you just created.

Can you please elaborate how to do this dot product in CCL for helicity term
