Use plain LbmPy bounce back boundary, but with streaming_pattern=pul, as we call it before the stream sweep. The patched boundar additional data handling is stil neded.
To my understanding, this accounts for hte fact that the C++ boundary implementaiton queries the fluid node (not the boundary node) for the boundary velocity.
