Particles in container penetrating through wall

Thanks,

This clarifies a lot. However there's one question. Is it possible to process tyFlow cache simultaneously with rendering as long as caching process is ahead of rendering proces, or do I need to wait caching to finish first.

Now the caching is half way there, and the mesh file is already more than 13 GB. Max became very unstable and the rendering scene wont start any more. Is there anything I can do to reduce the size of the cache file? Or should I maybe try to create cacheless simulation?
