There are many — GEANT4, PHITS, MCNP are the most common. Which one to use depends on which type of particle and energies you want to simulate, and what physical aspects of your problem you need the simulation to convey (energy deposition, particle flux, vacancy creation, etc.), as well as the source and transport medium geometries needed to adequately describe your problem.

You can use TRIDYN, SdTRIM, MD similation.

Dear Dr. Moussaab Belarbi , what link you have given is free software or one need to purchase the package? if free then please elaborate how to install. Thank you.
