WebDec 31, 2016 · You can use sympy.curl () to calculate the curl of a vector field. Example: Suppose F (x,y,z) = y 2 z i - xy j + z 2k, then: y would be R [1], x is R [0] and z is R [2] the unit vectors i, j, k of the 3 axes, would be … WebJan 18, 2015 · The curl of a 1-form A is the 1-form ⋆ dA. The divergence of a 1-form A is the function ⋆ d ⋆ A. The Laplacian of a function or 1-form ω is − Δω, where Δ = dd † + d † d. The operator Δ is often called the Laplace-Beltrami operator.
