the mesh size depends on the numerical scheme used to simulate the plasma:

if you use analytic equations (GlobalMaxwellBotzmannVOlDistrib) you must describe the smallest of either the secondary+photoelectron scales or the ion scales (Debye length, plasma frequency,...) if you use kinetic equations (PICVolDistrib) you must describe the electrons scales.

For the size of the domain, it is more a memory problem. With a typical 8Gb RAM (do not forget to divide by 2 - 3 if you use Windows) you can simulate a few 100000's cells.

Wich are the simulation size limits? I.e., how big (-100s m, ~1000m?) or how small (~10cm, 1cm?) can the simulations be? Can the code make good calculations with a mesh size ~0.1cm between vertices? Thank you!
