Use the Electron Production Rate node to add sources and sinks to the number density of electrons. Ionization processes lead to an increase in the number density of electrons. Similarly, attachment leads to a decrease in the number density of electrons. A production rate for new electrons can be specified with this feature.

Select or enter a value for a Production rate Re (SI unit: 1/m3·s) of new electrons. The value typically comes from The Heavy Species Transport Interface.
