Dear all, if we have a Function u and we want to calculate \frac{\partial{u}}{\partial{x}}, we use u.dx(0). Now I need to calculate the derivative of Function u with respect to a direction, I showed this direction in the following figure: [Screenshot from 2024-06-23 13-18-37] Does anyone know how…

The small snippet looks fine to me. The best thing to do is to test it with a known u and v and see if you get what you expected.
