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 … WebThe curl vector will always be perpendicular to the instantaneous plane of rotation, but in 2 dimensions it's implicit that the plane of rotation is the x-y plane so you don't really bother with the vectorial nature of curl until you get to 3 dimensional space. Then it starts to …
