Sets the div operator to 0 in conductors (for all elements of the same type)

Sets the div operator to 0 in conductors for all elements of the same type and computes the charges of the base conductors. The charges of the base conductors are the sums of the divergences in all the interface vertices between the base conductors and the insulators. As the divergence inside of the conductors is set to zero, we sum over all the nodes in the closure of the conductors. Remark: Only full-dimensional elements should be considered.

		vector_type &	u,
		size_t	fct,
		const DoFDistribution &	vertDD,
		const pot_vector_type &	cor
	)

private

Updates the grid function by the potential correction.

Computes the edge-centered correction from the vertex-centered (potential) one by applying the gradient operator.

Note that the edge-centered correction is considered only in the closure of insulators. There, it is the gradient of the vertex-centered (potential) correction. But in the conductors (as well as on the Dirichlet boundaries), the vertex-centered correction is constant by construction so that its gradient is 0 any way. (Adjacent conductors are concidered as one conductor in the projection, so that the different factors for the charges in different conductors does not violate the constant value of the vertex-centered correction in any separated piece of conductors.) For this, the function computes the gradient over the whole domain.

Parameters

[in]	domain	the domain
[in]	edgeDD	the edge DD
[out]	u	the vector to correct (to update)
[in]	fct	function in u to update
[in]	vertDD	the vertex DD
[in]	cor	the potential correction for u

		DenseMatrix< VariableArray2< number > > &	C
	)

private

Integrates div E over boundaries of conductors for elements of the same type.

Integration of div E over boundaries of conductors (for one type of elements) to get the capacity matrix. We compute only the lower triangular part of the capacity matrix: This matrix is symmetric.

Sets the base conductor indices for every vertex (for all elements of the same type)

Initializes 'vert_base_cond' with the indices of the base conductors according to the closure of the conductive subsets.

The attachment must be preinitialized with the default value -2 (for the insulators).
