Reply To: Better understanding of velocity vectors graphic in Fluent

Have you defined your own Velocity Magnitude? Because the one used in Fluent is uses all three components, whereas your vectors are only showing the x and y components. Those vectors in your circle are red despite being small because these cells have a large component of velocity in the z direction. If you were to create your own variable for the velocity magnitude using only v_x and v_y, then you would see these vectors be blue.
