Added-mass partitoned fluid-structure interaction solver for aorta dissection blood flow

Loosely or strongly coupled Dirichlet-Neumann (DN) partitioned fluid-structure interaction (FSI) algorithms are stable only if the density of the structure is much higher than that of the fluid. This requirement is difficult to achieve in hemodynamics where the density of blood is on the same order of magnitude as the density of arterial walls. The stability issue is even more pronounced when the blood vessel walls are surrounded by the blood flow from both sides, as is the case for an aortic dissection.
