Hey so probably a really simple question, but I'm stumped. How do you simplify:
ν∇⋅(ρν), where
ν is a vector
∇ is the "del operator"
⋅ indicates a dot product
ρ is a constant.
I want to say to do the dyadic product of v and ∇, but then you would get (v_x)*(d/dx) + ... which would be meaningless, so I'm thinking you do the dot product first, but I can't find an order of operations for algebra involving tensors of any order (except zero order of course).
Thanks in advance.
