Warning # 090

September 29, 2005, 11:31

Hi All,

I was runnning a combustor model in STAR CD 3.15 but when I am running the same model in STAR CD 3.24, I am getting following warning.

*** WARNING #090 *** VALUE ELOG*YPLUS OR ELOG*EFFVIS/(CAPPA*VISCOS) IS LESS THAN 1.1 AT 200 CELLS. UPLUS=YPLUS LAW IS USED. IF THIS SITUATION PERSISTS, INCORRECT RESULTS MAY BE OBTAINED.

The results vary by about hundred degrees, higher temperatures are obtained from 3.24.

Thanks,

If this warning persists after 200 iterations then you have to refine the mesh near wall region(I am assuming that you are doing a steady state analysis)
