concept of periodic

Asked by Leonard

Hi,
I am a bit confused about the concept of periodic.
Now, I am working at building a triaxial test framework, when I searched for examples of triaxial tests, I found there are actually two types of examples, i.e., periodic triaxial test and triaxial test. I wonder what is the difference between the two. By the way, I saw some commands like:
O.periodic=True,
Yade gives the description as 'Get/set whether the scene is periodic or not (True/False)', but I still don't know what this means. Is it related to periodic boundary?
Thanks in advance.

Hi,

Yes, periodic triaxial test and triaxial test differ in the sense the former uses periodic boundaries [1], whereas the latter use actual boundaries through rigid walls.

As for O.periodic = True, this is the command to call for the use of periodic boundaries [1].
