Description
We present a solver for the one-dimensional blood flow equations based on a discontinuous Galerkin (DG) method in space with implicit time stepping. One-dimensional blood flow simulations are computationally efficient and useful for studying pulse wave dynamics in complex vascular networks. The implicit DG formulation ensures stability on stiff network configurations without the restrictive time-step constraints of explicit schemes, enabling efficient largescale time integration. We demonstrate the parallel performance and accuracy of the solver on benchmark problems and on realistic vascular networks.
