Reply To: Overlap for the FD BC and the simultaneous use of Bouzidi and a Thermal lattice
Thank you very much for the bug reports!
I will take a closer on how to fix this in the general case but from your description this is definitiely something that should be handled differently. An overlap of 1 is correct for the interpolated velocity boundary by itself but doesn’t take into account the possibility of neighbor momenta requiring their own neighborhood – in the worst case this relationship could extend arbitrarily far. In a different context we are already investigating whether to communicate the momenta data from neighboring blocks instead of enabling only-partial computation from the overlap.
