warning # 90
 
I was running a micro combuster model in Star CD 3.15 it was ok, now when I am running same model in 3.24, I am getting following msg

*** WARNING #090 *** VALUE ELOG*YPLUS OR ELOG*EFFVIS/(CAPPA*VISCOS) IS LESS THAN 1.1 AT 180 CELLS.UPLUS=YPLUS LAW IS USED. IF THIS SITUATION PERSISTS, INCORRECT RESULTS MAY BE OBTAINED.

How can I fix this this problem?

Check your y+ values. You may need to use a different turbulence model (low Re vs. high Re) or turn on the hybrid wall functions (with a low Re model).
