Random fluctuations at the inlet boundary for LES
 
Hi CFX users

How can we add synthetic turbulence at the inlet for LES case. Is there a way to impose some sort of random fluctuations at the inlet boundary? Fluent and OpenFOAM seem to have such options but I could not find any option in CFX documntation. Thank you

Hi man,

i've used the random fluctuation at the inlet in my domain with UserFORTRAN. You have to build a routine to generate the randomic fluctuations... If you are still with this problem send me a message...
