FCSys.Species.'e-'.Graphite.Fixed

Fixed properties

Information

Assumptions:

1. The fluidity is infinite. All friction is by translational exchange with the the substrate (C+).
2. The thermal resistivity is infinite. All of the thermal conductance is attributed to the substrate (C+).
3. The conductivity is mapped to the mobility of the electrons by assuming that the mobility of the substrate (C+) is zero.

If consTransX, consTransY, or consTransZ is ConsTrans.dynamic (the default is ConsTrans.steady instead), then internal inductance is included according to the relative permeability (μ^*).

For more information, please see the Species model.

Extends from Ion (Base model for an ion).
