WebAug 18, 2024 · [CURLZ, CAV]= curl (X,Y,U,V) computes the curl z component and angular velocity perpendicular to z (in radians per time unit) of a 2D vector field U,V. The arrays X,Y define the coordinates for U,V and must be monotonic and 2D plaid (as if produced by MESHGRID). Now I need to calculate also the potential of these vectors. Webc = curl (V,X) returns the curl of symbolic vector field V with respect to vector X in three-dimensional Cartesian coordinates. Both the vector field V and the vector X must be …

Webin vector form as (u · ∇)u. We choose to numerically discretize the form on the left hand side, because it is closer to a conservation form. The incompressibility condition is not a time evolution equation, but an algebraic condi-tion. We incorporate this condition by using a projection approach [1]: Evolve the momen-
