free version limit could cause a crash?

There’s no limitation like that, it just seems like you’re running out of RAM.

Many thanks for your reply!
I almost managed to do almost the same scene with particle flow, with the same alembic cache, as an animated shape (0-179 frame in loop)
without running out of RAM, but would prefer the tyflow way of movements.
I also disabled the tyflow cache function.
Is there a solution to render a flow out (or preview) which is not fit into my RAM (64 GB) first?
(it is 24MB per frame)
I've already try with vray proxy also with the same result.
Thanks!
