warning in file star.info
 
Hello to everybody,

At the end of a run there is a warning in file star.info. *** WARNING #090 *** VALUE ELOG*YPLUS OR ELOG*EFFVIS/(CAPPA*VISCOS) IS LESS THAN 1.1 AT 30920 CELLS. UPLUS=YPLUS LAW IS USED. IF THIS SITUATION PERSISTS, INCORRECT RESULTS MAY BE OBTAINED. Do you know how can I correct this? Thank you

George

I also encountered the same problems, but it appeared at the beginning of the .info file. In my case, I applied the two-layer wall function model. How about your case?

I applied standard wall functions. Do you know how can we treat the problem?

it appears that the height of that cell is too small, which lies in the inner sublayer layer. So, at first, increase height of the first cell near the wall.

Thank you very much I will compute y+ and I will increase the height of the first cell above y+.
