About open Periodictiy boundaries.
Dear Alex and other developers:
I found out that in old version(3.1) the periodicity boundries enables simulation with feedback of particles that leave the end of the domain and are then re-injected creating a continuous flow such as shown in the new testcase.
However, In new versions(4.0) it is achieved by allowing particles that are near an open lateral boundary to interact with the fluid particles near the complimentary open lateral boundary on the other side of the domain.
Then , can you tell me the difference between both methods? for example in 3D wavemaker case, in old version, if a particle is out of boundary in Y direction, it will be inserted in other side?
in old version, does not it occur?
Thanks a lot for your help!

Sorry but not sure what you mean...

In CASEPERIODICITY the particles are moving in +X direction and there is periodicity in X axis.
In CASEWAVEMAKER the particles are moving in X direction but there is periodicity in Y axis.
I think the reason is also obvious...
