WARNING #090
Hi every one, I`m running a buoyancy problem with high Re k-Epsilon model. I`m getting the warning "WARING #090 *** VALUE ELOG*YPLUS OR ELOG *EFFVIS/(CAPPA*VISCOS) IS LESS THAN 1.1 AT 9806 CELLS.UPLUS=YPLUS LAW IS USED. IF THIS SITUATION PERSISTS,INCORRECT RESULT MAY BE OBTAINED" for my first iteration and the numbe r of cells decreases gradually and varies between 8 and 16. The results are converging with the residual tolerance of 10E-4. Do you think the results are valid ??? Any help is greatly appreciated.
Thanks, -SKC |
Re: WARNING #090
You should check where your areas of poor y+ values are. Are they in critical regions of the domain? I would think that 16 cells aren't too bad and that you can live the results.

Re: Error#076#
How to overcome this type of error it shows the message: Negative density found more than 100 cells

Re: Error#076#
You need to chekc on BC's and also try to reduce your under-relaxtion parameters to get a good convergence.
