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 ... WebDivergence and curl are two measurements of vector fields that are very useful in a variety of applications. Both are most easily understood by thinking of the vector field as representing a flow of a liquid or gas; that is, each vector in the vector field should be interpreted as a velocity vector.

Web“Gradient, divergence and curl”, commonly called “grad, div and curl”, refer to a very widely used family of differential operators and related notations that we'll get to shortly. We will later see that each has a “physical” significance. But even if they were only shorthand 1, they would be worth using. Webcurl (kɜrl) v.t. 1. to form into coils or ringlets, as the hair. 2. to form into a spiral or curved shape; coil. 3. to adorn with or as if with curls or ringlets. v.i. 4. to grow in or form curls …
