Hello

In 3dimensional case,

which of the following indicates the Negative w velocity at any node?

a)The flow of fluid towards the BOTTOM (from that node)

b) The flow of fluid towards the top Surface (from that node)

Hi

First of all, it's strongly advise to avoid twice posting, even you will have no answer to your post...

As W is along the Z axis, positive value indicate a movement from the bottom to the top and a negative value indicate a movement from the top to the bottom
