mariachi is on a distinguished road
hey friends,

i am doing LES of wing. i want to compare LES with URANS. as in URANS, we cannot record the fluctuating part of velocity or other variable, instead we get a mean time averaged solution, but LES is a more accurate solution towards the flow problem.

now i want to record or visualize these fluctuations so dat i can compare it with URANS which will offcourse show no fluctuations.

ive heard that UDF has to be written for this purpose. is it so???

and if it is, how to do it???

ill be really thankful for any help......
