One Dimensional Model

class pybamm.thermal.x_full.OneDimensionalX(param, options=None)

Class for one-dimensional (x-direction) thermal submodel. Note: this model assumes infinitely large electrical and thermal conductivity in the current collectors, so that the contribution to the Ohmic heating from the current collectors is zero and the boundary conditions are applied at the edges of the electrodes (at x=0 and x=1, in non-dimensional coordinates). For more information see [1] and [2].

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

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

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_boundary_conditions(variables)

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 pybamm.BaseSubModel.

Parameters:

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

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 a 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.
