hi, i am working on simulating air flow pattern of the ceiling fan.
In MRF method under frame motion i tried simulation giving -20 rpm and +20 rpm as the rotational speed . For both two cases flow pattern shows upward velocity vectors in solution.

any suggestions to make this flow vector in downward direction?

thanks in advance
