mitti New Member Join Date: Nov 2016 Posts: 15 Rep Power: 9	Hi all, probably an easy solution but I couldn't find anything to help me out. I need to implement an algebraic equation like that (this is physical meaningless reduction): $\overline{a_i}=C*\overline{a_j} \frac{\partial U_i}{\partial x_j}$ where a is a vector field, C a constant and U is velocity field. How do I do it? I got lost by the part where a depends on a.. Thank you
