Expression for a normal velocity component?

Hello,

I'm trying to constrain the normal velocity vector component to be zero in a curved surface.

I made a weak constraint node and typed in "u*(spf.nx)+v*(spf.ny)".
If I understand this correctly, does this mean that the x-velocity and the y-velocity components normal to the curve are zero?

Thank you!

TJ
