Stabilization approaches for the hyperelastic immersed boundary method for problems of large-deformation incompressible elasticity
Ben Vadala-Roth, Shashank Acharya, Neelesh A Patankar +2
The immersed boundary method is a mathematical framework for modeling fluid-structure interaction. This formulation describes the momentum, viscosity, and incompressibility of the…
