Sorry Robert, I noticed that I have not closed this thread yet. I
double-checked the units again and noticed that there seems to be an
arithmetic error here:

>> q = np.linalg.norm(v)/totalVolume # m^4/s divided by m^3 -> m^3/s

m^4/s divided by m^3  should be m/s, which is the average of the
velocity vectors. I guess we are missing the external area of cavity for
calculating the flux (average velocity vectors * area =flux). What am I
missing?

Thanks
Zoheir
