Inlet velocity expression
 
Hey there,

I'm looking to implement a parabolic velocity profile at the inlet of a square duct in CEL. The expression is -2x^2+6x-4.
Could you help me out please with the dimensions ?

Best regards,

You have not stated what the dimensions are - I will assume they are metres and m/s.

Then the CEL for your function will be
velocity = -2[m/s]*(x/1[m])^2+6[m/s]*(x/1[m])-4[m/s]

Thanks Glenn, the dimensional analysis was getting me stuck. I can't find any CFX documentation to help with this. Any ideas?

Best regards,
