Hi to all,

I am simulating a LES turbulent channelflow using channelOodles, i fixed the value of Ubar and i ran the case for few iterations, i would like to get the values of u_tau in order to estimate the corresponding Re_tau.
Does openFoam print out these values?
u_tau=(nu*(du_x/dy+du_z/dy))^0.5

Thanks in advance

please Hady try not to make a new thread for every new question you have. In this way, you make your chances to get answer lower and also make it harder for others to follow the topics. There are several posts on channelOodles. Post on one of them your question.

Have a nice day,
Maka

On the contrary some users gets an email alert (check Edit Profile) when one of the the threads that they used has a new question. As a result, your chance is higher to get an answer for a question if you managed to find a thread that "related to it". The last part is important otherwise, your message may be ignored. It is OK, I have done the same when I started. I just learned that by trial and error :-). Good luck with your computations. Have a nice day!

Best regards,
Maka
