Here is the caller graph for this function:

template<int dim>

virtual void FuelCellShop::Layer::HomogeneousCL< dim >::current_density	(	std::vector< double > &	current,
		std::vector< double > &	effectiveness
	)

inlinevirtual

This member function computes the current density production in the CL.

First argument is current density, and second is effectiveness, at all quadrature points in the cell. Since this is a macro-homogeneous layer, effectiveness is filled as 1.0
