it is nice to hear that you achieve stable boundaries for high Reynolds numbers. The term interpolated I mentioned before was related to the boundary naming that we have in OpenLB. Our implementation of the interpolated boundary is described in Latt et al. “Straight velocity boundaries in the lattice Boltzmann method” (BC4). Guo’s neq Extrapolation is also a good choice!
