ABSTRACT: This paper presents some biomedical applications that involve
fluid-structure interactions which are simulated
using the Immersed Finite Element Method (IFEM). Here, we first review the
original and enhanced IFEM methods that are suitable to model incompressible
or compressible fluid that can have densities that are significantly lower
than the solid, such as air. Then, three biomedical applications are studied
using the IFEM. Each of the applications may require a specific set of IFEM
formulation for its respective numerical stability and accuracy due to the
disparities between the fluid and the solid. We show that these biomedical applications require a fully-coupled and
stable numerical technique in order to produce meaningful results.
