An essential part in the simulation of blood flow in arteries is the incorporation of the arterial elasticity by modeling the vessel wall and its interaction with the fluid inside the vessel. We suggest a simple approach for modeling elastic walls in lattice Boltzmann simulations of arterial blood flow that produces physically correct results. We have developed a simulation software that implements this approach combined with the lattice Boltzmann method and conducted numerical experiments on a generic vessel model. Preliminary results presented in this work are promising and encourage using this method for further simulations with real physiological parameters in medical applications.
