Warning Errors

I often get the warning: "A vortex crosses the pressureopening". The results of an analysis when this warning is displayedare generally suspect.
I have tested physical models equivalent to the 3D flow models andI know they work much better than the analysis results (whenwarning is present). How do I deal with this problem? Refine themesh? Other comments?

Thanks,
