Detailed Description

template<typename T, typename X>
class Dune::PDELab::VectorDiscreteGridFunctionDiv< T, X >

Compute divergence of vector-valued functions.

Template Parameters

T	Type of VectorGridFunctionSpace.
X	Type of coefficients vector.

The grid function space should be a vector grid function space consisting of scalar-valued function spaces. The divergence will be a single component function.
