Fast Single Particle

class pybamm.particle.FastSingleParticle(param, domain)

Base class for molar conservation in a single x-averaged particle with uniform concentration in r (i.e. infinitely fast diffusion within particles).

Parameters:

• param (parameter class) – The parameters to use for this submodel
• domain (str) – The domain of the model either ‘Negative’ or ‘Positive’

Extends: pybamm.particle.BaseParticle

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)

For single particle models, initial conditions can’t depend on x so we arbitrarily evaluate them at x=0 in the negative electrode and x=1 in the positive electrode (they will usually be constant)

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.
