Periodic BC on Wedge

Hello everybody,

I am looking for a possibility to make use of symmetries (axisymmetry) in my geometry for my LIGGGHTS simulation.
I had a look into the Doc and found the possibility to create a wedge-region (e.g. a quarter of a cylinder). But according to the Doc, when I use the create_box command, LIGGGHTS would wrap the wedge-region with a rectangular block.
The thing I am looking for is the possibility to set a periodic boundary condition that links two faces that are not of the same dimension, e.g. the lower x-face with the lower y-face.

Example:
Is there the possibility to simulate a half/quarter/eighth of the binflow-tutorial (by C. Stoltz)?

Best regards
Harald

Hi Harald,

you are right, that would be a nice feature.
Unfortunately, this is not possible and not trivial to implement.

Sry.. I have no better news.
