LES and UDF... plz help!
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......
You must write a UDF or a scheme macro in order for you to be able to save the speed fluctuations at every time step.
can u give me some more details plzzz,
or if u can point me towards someone who has done some related work, maybe give me his email
ill be really thankful
