Detailed Description

template<int dim>
class FuelCell::Application::AppOhmic< dim >

The application can be used to simulate a electron transport through a porous media.

This class is used to solve a electronic transport problem using Ohm's Law.

The equation solved is written as follows: $\qquad \mathbf{\nabla} \cdot \left( \hat{\sigma}_{s,eff} \cdot \mathbf{\nabla} \phi_s \right) = 0 \quad \in \quad \Omega$

$\hat{\sigma}_{s,eff}$ is effective electron conductivity tensor [S/cm].

The governing equation in the weak form is actually linear and can be solved directly using a linear solver like UMFPACK or GMRES. The main file for this application should look like this:

* subsection Simulator
*  set simulator name = ohmic
*  set simulator parameter file name = data.prm
*  set solver name = Linear 
*  set Dakota direct = false 
* end
* 

NOTE: The solver name is set to Linear instead of the Newton solvers The lines below indicate how to setup your boundary and initial conditions. [Although initial conditions are not required for this problem it is advisable to use them just to see that the solver is working.]

* subsection Equations
* 
* subsection Electron Transport Equation
* 
*  subsection Initial data
*   set electronic_electrical_potential = 0: 0.1 # where 0 indicates the material_id setup in the grid and 0.1 is the electronic potential in V
*  end
* 
*  subsection Boundary data
*   set electronic_electrical_potential = 1: 0.4, 2:0.01 #where 1 & 2 denote the boundary ids and 0.4 and 0.01 are the electronic potentials in V at the respective boundary
*  end
* 
* end
*
