List of examples of various simulation settings

[Hemadityamalla]

Hi all,

I think it would be really helpful (for future work) if we put some effort have a list of examples where we demonstrate how various settings in the cfg file affect the simulation results.
Currently, we have a set of .cfg files that demonstrate a particular setup, e.g., multiple pulses, gas heating, 3D.
But we dont have any examples for the numerical settings, e.g., mesh refinement, limiting fluxes, interpolation settings of transport files, dt settings, etc.
The motivation for this opening this issue is that many researchers who tend to use this package dont seem to have a working knowledge of numerical methods which might result in them producing incorrect results.
Then they tend to spend a lot of time trying to understand what is going wrong.
Consequently, there is an over dependence on a single person (usually the code maintainer), which is really inefficient.
So please contribute ideas/working examples (in the form of a .cfg file of a simulation setup, or an image demonstrating the functionality.) which will act as a reference guide for future users of this package. E.g., see the image attached that demonstrates how the streamer length varies when varying 'derefine_dx' by a factor of 0.5.

Cheers
