| Summary: | Fluid-Structure Interaction engages with complex geometry especially in biomechanical
problem. In order to solve critical case studies such as cardiovascular diseases, we need the
structure to be flexible and interact with the surrounding fluids. Thus, to simulate such systems, we
have to consider both fluid and structure two-way interactions. An extra attention is needed to
develop FSI algorithm in biomechanic problem, namely the algorithm to solve the governing
equations, the coupling between the fluid and structural parameter and finally the algorithm for
solving the grid connectivity. In this article, we will review essential works that have been done in
FSI for biomechanic. Works on Navier–Stokes equations as the basis of the fluid solver and the
equation of motion together with the finite element methods for the structure solver are thoroughly
discussed. Important issues on the interface between structure and fluid solvers, discretised via
Arbitrary Lagrangian–Eulerian grid are also pointed out. The aim is to provide a crystal clear
understanding on how to develop an efficient algorithm to solve biomechanical Fluid-Structure
Interaction problems in a matrix based programming platform. |
