Hello to all of you FreeFem users,
After solving my system of PDE, I would like to compute the maximum value of my solution and the corresponding coordinates in my domain.
I found on another thread that I can do “u.max” to find the maximum on the mesh (where u is my solution) but then how can I find the corresponding (x,y) coordinates ?
I know that the result of this procedure won’t be the true maximum if I use P2 elements because it gives the maximum value on vertices of the mesh but since I’m using a fine mesh it’s not really important, I don’t need a huge precision.
Thank you in advance.
