Bruggeman Model

class pybamm.tortuosity.Bruggeman(param, phase, options=None, set_leading_order=False)

Submodel for Bruggeman tortuosity

Parameters

• param (parameter class) – The parameters to use for this submodel

• phase (str) – The material for the model (‘electrolyte’ or ‘electrode’).

• options (dict, optional) – A dictionary of options to be passed to the model.

• **Extends (** pybamm.tortuosity.BaseModel) –

get_coupled_variables(variables)

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.

Parameters

variables (dict) – The variables in the whole model.

Returns

The variables created in this submodel which depend on variables in other submodels.

Return type
