An explicit composite leading and first order solution to solid phase current conservation with ohm’s law. Note that the returned current density is only the leading order approximation.
A public method that creates and returns the variables in a submodel which require variables in other submodels to be set first. For example, the exchange current density requires the concentration in the electrolyte to be created before it can be created. If a variable can be created independent of other submodels then it should be created in ‘get_fundamental_variables’ instead of this method.
A method to set the boundary conditions for the submodel. Note: this method
modifies the state of self.boundary_conditions. Unless overwritten by a
submodel, the default behaviour of ‘pass’ is used a implemented in
variables (dict) – The variables in the whole model.
