Wycisk Open Circuit Potential#

class pybamm.open_circuit_potential.WyciskOpenCircuitPotential(param, domain, reaction, options, phase='primary')#

Class for open-circuit potential with hysteresis based on the approach outlined by Wycisk :footcite:t:’Wycisk2022’. This approach employs a differential capacity hysteresis state variable. The decay and switching of the hysteresis state is tunable via two additional parameters. The hysteresis state is updated based on the current and the differential capacity.

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:: dict

get_fundamental_variables()#

A public method that creates and returns the variables in a submodel which can be created independent of other submodels. For example, the electrolyte concentration variables can be created independent of whether any other variables have been defined in the model. As a rule, if a variable can be created without variables from other submodels, then it should be placed in this method.

Returns:: The variables created by the submodel which are independent of variables in other submodels.
Return type:: dict

set_initial_conditions(variables)#

A method to set the initial conditions for the submodel. Note: this method modifies the state of self.initial_conditions. Unless overwritten by a submodel, the default behaviour of ‘pass’ is used as implemented in pybamm.BaseSubModel.

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

set_rhs(variables)#

A method to set the right hand side of the differential equations which contain a time derivative. Note: this method modifies the state of self.rhs. Unless overwritten by a submodel, the default behaviour of ‘pass’ is used as implemented in pybamm.BaseSubModel.

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