Hendrix, John
Thanks for clarifying that. Reasons I was interested in win x-ray - bse appeared better - but as Hendrix points out on seperate post can use casino v3. Also win x-ray simulate charge in insulating samples - but this assumes a grounded coat i.e. charge at surface = 0: so don't need to add it as geometry. - although I surpose you can't model x-rays passing through gold coat vs carbon coat under electric field.#

Hi Ben,
For winxray, I use a simple model of charging with a thin coating at the surface. The main results were published in this paper:
Demers, H. & Gauvin, R. X-ray Microanalysis of a Coated Nonconductive Specimen: Monte Carlo Simulation Microscopy and Microanalysis, 2004, 10, 776-782
But if you can read french I can send you my master thesis with more detail.
If you want to model insulator with the effect of Au versus C coating. You can just add the x-ray absorption from the layer to the results given by winxray (if you are at high accelerating voltage, this approximation should be good). Also PENELOPE can simulate magnetic and electric field, but I never try it. If you are interested look at Sorbier PhD thesis.
Regards,
Hendrix
