ADGasElectronMoments in two different blocks with different gases?

[ghost]

Edit: I tried something simple: I took a simple DC argon discharge model, and broke up the mesh into two blocks. I ran three simulations: one with a single block for the gas, one with two blocks but every kernel/material/action acted on block = '0 1', and one with the ADGasElectronMoments/GasConstants/etc doubled, one for each block. All three work and ran identically! I tried to expand this by having a DriftDiffusionAction acting in block 0 and block 1 separately with the same variable names for the species, but this did not work. Overall, I'm happy!

I was wondering whether or not one could run a Zapdos simulation with two ADGasElectronMoment material blocks corresponding to a geometry where two materials/gases have distinct separation rather than a homogeneous mixture, where the electrons experience different scattering, ionization, excitation, etc cross-sections between the two gases? Furthermore, could this two material/gas domain be solved with a single electron species, rather than splitting it up between em_gas1 and em_gas2?

To provide a concrete example, SF6 gas is used in high-voltage switching devices for circuit breakers at electric substations. SF6 is used because it is very resistant to electrical breakdown to prevent the formation of arcs between metal contacts within the device. However, if a leak forms in the walls of the device (such as due to puncture or corrosion), SF6 will leak out and some air will enter, causing the formation of arcs to be much more likely. Because SF6 is much denser than air (plenty of YouTube videos exploring this), it could be assumed that the separation between air and SF6 is distinct with a boundary layer, much like oil and water. One might want to model the plasma dynamics of such a scenario, in which case both layers would need to be fully resolved as partially ionized gases.

To my knowledge, I haven't seen any examples of such a practice in any of the Zapdos use-cases, so I am very curious if Zapdos could handle this sort of set up!
