WebThe curl in 2D is sometimes called rot: rot ( u) = ∂ u 2 ∂ x 1 − ∂ u 1 ∂ x 2. You can also get it by thinking of the 2D field embedded into 3D, and then the curl is in z direction, that is, it only has one component. As you rightly say, it is in essence the same as the div: div ( u) = rot ( u ⊥), where u ⊥ = ( − u 2, u 1).
