Fast discrete Cell Volume Tracking for Blood Flow Simulations using the Lattice Boltzmann Method — •Moritz Lehmann, Sebastian Müller, and Stephan Gekle — University of Bayreuth, Germany

The Lattice Boltzmann Method (LBM) is often used to simulate the movement of red blood cells through blood vessels via the immersed boundary method. However, the basic model does not include the different fluid viscosities of the inside of cells and the blood plasma, which also affect cell deformation. For taking into account multiple viscosity domains, we present a fast tracking algorithm that can determine whether any lattice point of LBM is located inside or outside an arbitrarily enclosed cell volume and we investigate how a viscosity change affects cell deformation.
