Reaction-driven Model

class pybamm.porosity.ReactionDriven(param, options, x_average)

Reaction-driven porosity changes as a multiple of SEI/plating thicknesses

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

  • options (dict) – Options dictionary passed from the full model

  • x_average (bool) – Whether to use x-averaged variables (SPM, SPMe, etc) or full variables (DFN)

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


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.


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


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

Return type:



A method to set events related to the state of submodel variable. Note: this method modifies the state of Unless overwritten by a submodel, the default behaviour of ‘pass’ is used a implemented in pybamm.BaseSubModel.


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