    Hi ssss!

    Div Curl F = 0

    See e.g. here.

    Re: Divergence Curl

    I don't understand what you mean by "Div Curl F(F bar not only F)".

    Not that I'd necessarily be able to solve it if I understood it, but maybe someone else would.

    I believe the OP meant that when he wrote F, he did not just mean F, but F with a bar over it.

    There are two kinds of Divergence Curl F and FwithBar(F bar) , so I want to know the value of both

    I'm afraid there's only one version:

    \nabla \cdot (\nabla \times \vec{\mathbf{F}}) = \text{div } \text{curl } \vec{\mathbf{F}} = 0

    Curl is an operator that can only work on a 3 dimensional vector.
