No, OpenLB currently doesn’t support local grid refinement. Various approaches exist as prototypes but it is not clear when this will be at a stage where we include it in a release as most efforts are currently focused on improving general performance and supporting GPUs.

Thus the bstep2d case only uses a fixed resolution for the whole lattice. The other M resolution is an remainder from development, thanks for pointing out this possible source of confusion!
