  The so-called 'raspberry' model refers to the hybrid lattice-Boltzmann and
Langevin molecular dynamics scheme for simulating the dynamics of suspensions
of colloidal particles, originally developed by [V. Lobaskin and B. D\"unweg,
New J. Phys. 6, 54 (2004)], wherein discrete surface points are used to achieve
fluid-particle coupling. This technique has been used in many simulation
studies on the behavior of colloids. However, there are fundamental questions
with regards to the use of this model. In this paper, we examine the accuracy
with which the raspberry method is able to reproduce Stokes-level hydrodynamic
interactions when compared to analytic expressions for solid spheres in
simple-cubic crystals. To this end, we consider the quality of numerical
experiments that are traditionally used to establish these properties and we
discuss their shortcomings. We show that there is a discrepancy between the
translational and rotational mobility reproduced by the simple raspberry model
and present a way to numerically remedy the problem by adding internal coupling
points. Finally, we examine a non-convex shape, namely a colloidal dumbbell,
and show that the filled raspberry model replicates the desired hydrodynamic
behavior in bulk for this more complicated shape. Our investigation is
continued in [J. de Graaf, et al., J. Chem. Phys. 143, 084107 (2015)], wherein
we consider the raspberry model in the confining geometry of two parallel
plates.
