Hello everyone, I have created a 2D curve mesh (1D topological dimension) like this: [image] I need to use and visualize the normal unit vector, I looked at some post but in these they use a 3D mesh, is there a way to compute the normal unit vector to use in a variational formulation, Also, her…

Note that when you use linear elements (straight elements), the divergence of the normal is 0 on every element (since the normal is constant on every line segment. If you run your code for a while, you will see that the normal is updated, but H will always remain 0, as the elements are not curved. …

This worked perfectly, thank you Dokken.
