Dune::FieldVector< typename Element::Geometry::GlobalCoordinate, PrimaryVariables::dimension >	Dumux::evalGradients (const Element &element, const typename Element::Geometry &geometry, const typename FVElementGeometry::GridGeometry &gridGeometry, const CCElementSolution< FVElementGeometry, PrimaryVariables > &elemSol, const typename Element::Geometry::GlobalCoordinate &globalPos)
	Evaluates the gradient of a given CCElementSolution to a given global position. This function is only here for (compilation) compatibility reasons with the box scheme. The solution within the control volumes is constant and thus gradients are zero. One can compute gradients towards the sub-control volume faces after reconstructing the solution on the faces.
