FIDYST vs SIMION

Both stand on simulation software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.

SIMION provides field solving, particle tracing, geometry tools, and programming interfaces for specialized charged-particle modeling. Users should account for its quasistatic limits and demo restrictions.
