Hi everyone!
I was wondering if it is somehow possible to define a region, introduce particles on it through the command create atoms and insert them to another region.
For example, create a cylinder full of particles, creating a pack, and drop it to a surface. Is that possible or the closest option is using the insert/pack command?
Thanks in advance!

Yes, but ...
.. you will not get a dense packing bc. insert packs brute-force-insert-algorithm is somehow limited to I think 30% voidfraction.
I would use fix insert/stream to pour the particles into the cylinder and than lift up the cylinder using fix move mesh to measure the angle of repose.
See this videos how I did it:

Yes, fix insert/pack is limited to 30% particle volume fraction. But you can use fix insert/stream or you can grow the particles over time - there is also an example for this in the public release

Thanks for your reply and the videos Christoph, I see what you mean. I think the insert/stream will be the option for me!!
