vishal_s is on a distinguished road
I m am trying to simulate a jet flow.My jet is coming from top to bottom but when plotting the velocity profile in the y direction, it is giving positive values. Isn't it going to be negative?? can you please tell me, how to reverse the profile in the plot.

I have attach the plot and pic .

Thanks in advance
