Immersed boundary finite element method for blood flow simulation

We present an efficient and accurate immersed boundary (IB) finite element (FE) method for numerically solving the incompressible Navier–Stokes equations. Particular emphasis is given to internal flows with complex geometries (blood flow in vasculature system). IB methods are computationally costly flows, mainly due large percentage of grid points that lie outside domain. In this study, we apply a local refinement strategy, along domain reduction approach, order reduce covers increase nodes fall inside The proposed utilizes FE solver incremental pressure correction scheme (IPCS), condition enforced solve transient, verify accuracy numerical using analytical solution Poiseuille cylinder. further examine applicability by considering within geometries, such as blood aneurysmal vessels aorta, configurations which would otherwise be extremely difficult most methods. Our offers high accuracy, demonstrated verification examples, efficiency, through geometry on off-the-shelf laptop computer.
