regarding blower analysis

Hi
I am working on blower analysis.I gave mass flow rate of 0.58kg/s at the inlet and pressure outlet as zero guage pressure.after the convergence i am getting negative mass flow rate at the outlet..plz help me..

Check the following things
first try to use a velocity inlet instead if mass flow inlet.

Second sometimes fluent gives negative value because the direction of flow in against the positive axis .
may be your fluid is going out in the negative direction.

thanks
shk
