Query: Direct 0D-3D coupling of a lattice Boltzmann methodology for
  fluid-structure hemodynamics simulations   This work introduces a numerical approach for the implementation and direct
coupling of arbitrary complex ordinary differential equation- (ODE-)governed
boundary conditions to three-dimensional (3D) lattice Boltzmann-based fluid
equations for fluid-structure hemodynamics simulations. In particular, a most
complex configuration is treated by considering a dynamic left ventricle-
(LV-)elastance heart model which is governed by (and applied as) a nonlinear,
non-stationary hybrid ODE-Dirichlet system. The complete 0D-3D solver,
including its treatment of the fluid and solid equations as well as their
interactions, is validated through a variety of benchmark and convergence
studies that demonstrate the ability of the coupled 0D-3D methodology in
generating physiological pressure and flow waveforms -- ultimately enabling the
exploration of various physical and physiological parameters for hemodynamics
studies of the coupled LV-arterial system. The methods proposed in this paper
can be easily applied to other ODE-based boundary conditions (such as those
based on Windkessel lumped parameter models) as well as to other fluid problems
that are modeled by 3D lattice Boltzmann equations and that require direct
coupling of dynamic 0D conditions.
