The Bouzidi BC only models the reconstruction of the missing populations at the boundary, including a velocity correction if necessary (this is what is set up by setBouzidiVelocityBoundary).

In order to have a general moving geometry, an additional refill step to reconstruct the populations of previously solid cells is required. We have various implementations of such refill steps but currently they are not included in the public release. If you want, I can advise you on how to implement a refill step suited to your particular application. Alternatively, I would suggest to take a look at HLBM resp. our resolved particle code. This is a validated FSI approach that is available in the current public release.
