If by the same result, you mean the oxygen atoms pass through the Fe crystal without even slowing down (as in your original movie), then I can not explain it. But you should probably do some more testing.

one test that i suggest you should do is to not use fix deposit, but
use the create_atoms random command to create some oxygen atoms atop
the surface before you start the run, give them a (small!) velocity
toward the surface and check that out instead.

hello,
thank you Axel for your suggestion, i have tested it in previous work to creat atoms on the top of substrate with zerro velocity.
i always get the same thing: the oxygen atoms pass through the substrate without slowing down.
can i anyone please; send me a script example that have been successfully worked .
thank you in advance.

how is it possible that your atoms pass through the substrate when you
assign them a zero velocity? atoms may be absorbed into the slab or not.
are you certain that you do not assign a velocity? and if yes, is that
value meaningful. if your deposit particle velocity is very large, atoms
will pass through the slab like any high-speed projectile will do.
