Detailed Description

template<int dim>
class FuelCellShop::PostProcessing::ORRCurrentDensityDataOut< dim >

Class used to evaluate the ORR current density, overpotential, effectiveness and the oxygen coverages (when applicable) at catalyst layer DoF point in the finite element mesh.

Child of DataPostprocessor (deal.II post-processing class used in DataOut class).

See step-29, step-32 and step-33 in the deal.II website for more details about this class.

Usage

This class is used in the data_out section of any application. It requires a pointer to SystemManagement, a pointer to the catalyst layer object for which you would like to compute the current density, and a pointer to OperatingConditions object.

* AppCathode<dim>::data_out(const std::string& filename,
*                           const FuelCell::ApplicationCore::FEVectors& src)
* 
* // --- Find solution and assign solution interpretations ---
* (...)
* 
* // --- Create vector of PostProcessing objects ---
* std::vector< DataPostprocessor<dim>* > PostProcessing;
* 
* // --- cathode_current --- For instance, on CCL object.
* // Create the post processing object and push it to the vector.
* FuelCellShop::PostProcessing::ORRCurrentDensityDataOut<dim> cathode_current(&system_management, CCL, &OC);
* PostProcessing.push_back(&cathode_current);
*
* // Outputting
* DoFApplication<dim>::data_out(filename,
*                               solution, // This is initialized in the initial part of the data_out function
*                               system_management.get_solution_names(),
*                               PostProcessing);

virtual

Member function used to calculate the current density.

Its inputs are

a vector representing values of the function (which is here vector-valued) representing the data vector given to DataOut::add_data_vector, evaluated at all evaluation points where we generate output
a tensor objects representing the first derivative (not used and not given properly since in the constructor we specified that only solution values need to be updated)

The derived quantities are returned in the computed_quantities vector.

Remember that this function may only use data for which the respective update flag is specified by either the constructor or get_needed_update_flags.

template<int dim>

virtual std::vector<DataComponentInterpretation::DataComponentInterpretation> FuelCellShop::PostProcessing::ORRCurrentDensityDataOut< dim >::get_data_component_interpretation ( ) const

virtual

Function that states if the output functions are a scalar or a vector.

template<int dim>

virtual std::vector<std::string> FuelCellShop::PostProcessing::ORRCurrentDensityDataOut< dim >::get_names ( ) const

virtual

Function that provides the names of the output variables.

In this case, current density, overpotential, effectiveness, and oxygen coverages (if applicable). The latter is set to one if the model is macro-homogeneous.

template<int dim>

virtual UpdateFlags FuelCellShop::PostProcessing::ORRCurrentDensityDataOut< dim >::get_needed_update_flags ( ) const

virtual

Flags to be updated in each cell when computing the solution.

template<int dim>

void FuelCellShop::PostProcessing::ORRCurrentDensityDataOut< dim >::set_oxygen_density_name ( std::string name )

inline

For the case of multi-component solvers, we need to specify which one of the variables contains the oxygen concentration, e.g., density_species_1, density_species_2 and so on.

Provide this value here.
