Detailed Description

template<class GridFunction>
class Dune::ACFem::DivergenceOperatorParts< GridFunction >

For a given grid-function define a model implementing the weak divergence.

In formulas: this fragment implements the integral

\[ \int_\Omega \partial_i v_i \, q \]

Here q is a scalar test function.

Parameters

GridFunction

The type of the function the weak divergence has to be computed from. This must be a grid-function, i.e. it has to carry a local function, and must have dimRange == dimDomain.
