Web19 de out. de 2024 · 1 Answer Sorted by: 2 As stated by Ninad, If T has a divergence it must be a vector field. And vector fields don't have gradients. But I think I see what you are looking for. If you have a vector field with divergence 0, it means your function T can be expressed as the curl of some other function ( locally ). Why is that? It helps to notice that: Web26 de fev. de 2015 · Divergence of the gradient = Laplacian. Standard way to do it is to use finite differences. Look for example at http://en.wikipedia.org/wiki/Discrete_Laplace_operator and you'll find the classic 2nd order 5-points stencil formula. (I'm assuming you have some basic understanding of finite difference schemes.) Share Improve this answer Follow hearts 2 handbags etsy
