Yes, the BounceBack dynamics in OpenLB model full-way bounce back in all releases, including 1.4.
Can you show your post processor attempt that did not work well?
In any case, the solid nodes where the populations are streamed to prior to executing half-way bounce back do not need to collide (i.e. you can use the NoDynamics
). During the PostStreaming
stage you can then copy the streamed populations back to the opposite directions of the non-solid cell they came from.
