Aug 28 2020 Relevant Equations Divergence theorem Good day all my question is the following Is it correct to after calculation the new field which is the curl of the old one to use the divergence theroem on the volume shown on that picture The divergence theorem should be applied on a closed surface can I consider this as closed Thanks a lot The divergence Gauss theorem holds for the initial settings but fails when you increase the range value because the surface is no longer closed on the bottom. This states that the volume integral in of the divergence of the vector valued function F is equal to the total. If F is a C1 vector eld whose domain includes Dthen ZZ D FdS ZZZ D rFdV The theorem is sometimes called Gauss theorem.
