I am getting a negative value of Velocity in my Flow Simulation analysis. It is not much, something like - 0.5 m/s
This made me puzzled: How can a velocity of a wind have a negative value???
I know that pressure can have a negative and positive value. Positive value of wind will act like a compressional force towards the object. And negative value of pressure will act like a suction force.
But velocity can only take positive value. How can a velocity take a negative value?
Did I just miss some of the physics classes, or is this just Flow Simulation error?
Thank you for the replies.
