Numerical computations can be challenging, particularly in three dimensions, due to the presence of moving boundaries and complex geometries; methods which combine ease-of-implementation and computational efficiency are therefore needed. A recently-proposed method to discretise the regularised Stokeslet boundary integral equation without the need for a connected 'mesh' is applied to the inertialess locomotion ","authors_text":"David J.
