We use two different sub-gridscale lattice Boltzmann methods to simulate the swimming motion of a model swimmer. We systematically characterise the discretisation errors associated with placing a continuous object on a grid, and place limits on how low the Reynolds number needs to be in order to reach the characteristic zero Reynolds number regime.
