I am new to CFX
 

hi there I am new to CFx in General and I would like to know How do I get values of eddy length scale to input as an inflow boundary condition in a case where I want to use air at a specific speed? (is it a value that depends on the turbulence intensity???) Any help will be appreciated

regards sac

Use autocompute length scale if you aren't sure about it. Refer to solver theory about the formula used to compute the length scale. If you have experimental data, then just apply it directly.
