This case shows cardiovascular flow in a patient-specific thoracic aorta. Incompressible fluid (blood) and hyper-elastic solid (arterial wall) are interacted in a pulsatile flow. The incompressible Navier-Stokes equations in the ALE (arbitrary Lagrangian-Eulerian) frame govern the fluid motions, and the large-deformation formulation is used for solid motions. A technical novelty of this FSI method is its ability to accommodate non-matching interfacial discretizations, which is advantageous for geometrical flexibility in mesh generation. The kinematic/kinetic interfacial conditions are weakly enforced at the fluid-structure interface using the VMDG (Variational Multiscale Discontinuous Galerkin) method.
