static _mapFactory * | get_mapFactory () |
Virtual class used to provide the interface for all MembraneLayer children.
No object of type MembraneLayer should ever be created, instead this layer is used to initialize pointers of type MembraneLayer. The class has a database of children such that it will declare all necessary parameters for all children in the input file, read the input file, create the appripriate children and return a pointer to MembraneLayer with the children selected.
All public functions are virtual but the static functions used to declare parameters and to initialize a pointer of MembraneLayer, i.e. declare_all_MembraneLayer_parameters, set_all_MembraneLayer_parameters and create_MembraneLayer.
In order to create a membrane layer within an application, the following steps need to be taken.
First, in the application .h file, create a pointer to a MembraneLayer object, i.e.
This pointer object will be available anywhere inside the application. Because we do not want to worry about deleting the pointer afterwards, we use a Boost pointer which has its own memory management algorithms. See the Boost website for more information
Once the pointer is available, we need to do three things in the application
The object is ready for use now.
Here is a code example from ??.cc:

This information in then used in layer_generator.h in order to create the correct object depending on the specified concrete type of layer selected such as DummyGDL or SGL24BA.

Set those solution variables which are constant in the particular application.
If the effective properties in the layer depend on other variables that are usually part of the solution vector but are assumed to be constant in this simulation, the const solution value should be passed to the class using this member function. This method should be called in the initialization section of the application. This function takes value to be set as the first argument and the VariableNames as second argument. For instance, it's required to store constant temperature value for an isothermal application, in that case this method can be used. e.g., in order to set temperature as 353.0
[Kelvin
] in the layer, you can use the following code:
If temperature_of_REV is passed using this method, it also sets the temperature [Kelvin
] values in the electrolyte object.
