WebFor the representation of a divergence-free vector field defined on a bounded simply connected domain of $\mathbb{R}^3 $ with a smooth boundary by its curl and its normal component on the boundary, a mixed formulation also involving a vector potential is proposed. The vector fields are discretized with help of curved finite elements that are ... WebQuestion: Express 〈3x+2y,4x+8y,0〉 as the sum of a curl free vector field and a divergence free vector field. 〈3x+2y,4x+8y,0〉= + , where the first vector in the sum is curl free and the second is divergence free. (For this problem, enter your vectors with angle-bracket notation: , not in ijk-notation.)
