poisson

openpnm.models.physics.ionic_conductance.poisson(target, pore_permittivity='pore.permittivity', throat_permittivity='throat.permittivity', size_factors='throat.diffusive_size_factors')[source]

Calculate the ionic conductance of conduits in network (using the Poisson equation for charge conservation)

Parameters

  • target (OpenPNM Base object) – Object with which this model is associated. This controls the length of the calculated array, and also provides access to other necessary properties.

  • pore_permittivity (str) – Name of the dictionary key on target pointing to the array containing values of pore permittivity

  • throat_permittivity (str) – Name of the dictionary key on target pointing to the array containing values of throat permittivity

  • size_factors (str) – Name of the dictionary key on target pointing to the array containing values of conduit size factors’

Returns

values – A numpy ndarray containing the computed values of ionic conductance

Return type

ndarray
