WebCurl is simply the circulation per unit area, circulation density, or rate of rotation (amount of twisting at a single point). Imagine shrinking your whirlpool down smaller and smaller while keeping the force the same: … WebThe definition of curl as microscopic circulation is a little more subtle than it just being a measure of the rotation of the vector field. Curl-free macroscopic circulation In the vector field pictured below, there is clear macroscopic circulation of the vector field around the z …

WebI'm stuck on the notation of the 2d curl formula. It takes the partial derivatives of the vector field into account. I believe it says the "partial derivative of the field with respect to x minus the partial derivative of the field with respect to y", but I'm not certain. Since I'm using noise to drive this vector field, I'd like to use finite ...
