TRANSPORT vs TRANSPORT2

[gilrrei]

I couldn't understand the difference between the TRANSPORT and TRANSPORT2 ELEMENTS sections even after looking into the source code 😅 Could somebody help out? When do I use which?

I think it is used if you have two distinct transport domains with different physics.

I believe that the artherosclerosis framework has done that. However, we have removed it from 4C. I don't know, if there are other use cases.

It is also used in the context of space-charge-layers for the simulation of solid-state-batteries.
