Hello Robert,

Thanks for your reply.

>Are you sure "he" is using periodic boundary conditions? If so, how do
you know? Is there a script for this video?

There is not a script for this video. I did not clearly understand the
meaning of 'periodic packing' in the title.

>You can create particles at any time/location that you wish using the
basic python interface

I will try to use the python interface.

Cheers
Peter

Status: Needs information => Answered

Jan Stránský proposed the following answer:
Hello,

You have several options:
- as suggested by Robert, implement the particle creation "manually" (search 
O.bodies.append, PyRunner etc.)
- using existing features - see examples [1,2,3] (also available in the source 
code in "examples" directory)

cheers
Jan

Robert Caulk requested more information:
Hello,

Are you sure "he" is using periodic boundary conditions? If so, how do
you know? Is there a script for this video? Also, we typically request
that people do not post external links [1] like this.

>So, is there a similar method in Yade that can achieve continuous
particles flow?

You can create particles at any time/location that you wish using the
basic python interface [2].

[Yade-users] [Question #693542]: Conveyor factory with periodic packing

2020-10-20 Thread Peter
New question #693542 on Yade:
https://answers.launchpad.net/yade/+question/693542

Hi everyone,

In this video[1], he simulated a conveying factory with WooDEM. It seems that 
he used 'periodic packing' method to continuously generate particles.

I have looked examples of Periodic Boundaries in yade, but did not find a 
similar method. So, is there a similar method in Yade that can achieve 
continuous particles flow?

 I will appreciate your help in answering my questions.

Thank you,
Peter
