Some advances in modeling multiphysics-biomedical applications

Publisher Summary The finite element analysis of biomedical applications requires powerful solid, fluid, and multiphysics capabilities. This chapter highlights some developments in finite element methods for the multiphysics problems encountered and provides three examples to demonstrate these capabilities. The first is an illustrative multiphysics problem showing fluid-structure interaction (FSI), flow through porous media, thermal coupling, and mass transfer. Frequently, in biomedical applications, FSI capabilities are needed. The FSI capabilities relevant to the biomedical field include coupling along solid-fluid boundaries, which is essential for modeling blood circulation problems such as those involving arteriosclerosis, aneurysms, grafts, endovascular stents, or heart valves. The second example is a coupled FSI problem involving blood flow through a stenotic artery. The third example involves a helmet impact simulation.
