Robert Caulk proposed the following answer:
Hello,

Please review our standard method for saving and loading simulations [1].
Also consider searching thru this forum for keywords of “save” and “load”.
Maybe O.save and O.load. This question is frequently asked in various ways,
I’m certain you’ll find example usages for it.

If you still have an issue after using our standard save load method.
Please read thru [2] and consider adding the requested MWE if you seek
accurate assistance.

> The first file save the VTK files and the .yade file, that I import in the
> second file. By the way, I have an error when I launch the second one:

> In particular, I noticed that actually the file/directory doesn't exist:
> in fact, in the error that I reported, is written the 367434 iteration, but
> from the first file, last VTK files that was saved is the 364752.
