Detailed Description
template<int dim>
class Charge< dim >
A convection diffusion equation to model the transport of charges:
![\[ q_t + \nabla\cdot (q \mathbf{u} ) = \nabla \cdot \left[ K(\phi) \nabla \left( \lambda q + V \right) \right], \quad \text{ in } \Omega \]](form_4.png)
with boundary condition
![\[ K(\phi) \nabla\left( \lambda q + V \right) \cdot \mathbf{n} = 0, \quad \text{ on } \Gamma. \]](form_5.png)

typedef IteratorGroup<4,typename hp::DoFHandler<dim>::active_cell_iterator> Charge< dim >::Iterator [protected] |
We group the iterators of this problem and the problems this one takes information from as follows:
-
Iterator[0]: this. -
Iterator[1]: Voltage. -
Iterator[2]: Phase Field, from CahnHilliard. -
Iterator[3]: Velocity
