Many numerical studies of blood flow impose a rigid wall assumption due to the simplicity of its implementation compared to a full coupling to a solid mechanics model. In this paper, we present a localised method for incorporating the effects of elastic walls into blood flow simulations using the lattice Boltzmann method. We demonstrate that our approach is able to more accurately capture the flow behaviour expected in an elastic walled vessel than a rigid wall model and achieves this without a loss of computational performance. We also demonstrate that our approach can capture trends in wall shear stress distribution captured by fully coupled models in personalised vascular geometries.
