Quasi-simultaneous coupling methods for partitioned problems in computational hemodynamics

The paper describes the numerical coupling challenges in multiphysics problems like simulation of blood flow compliant arteries. In addition to an iterative between fluid and elastic vessel walls, i.e. fluid-structure interaction, also a detailed 3D local (arterial) model more global 0D (representing circulation) is analyzed. Most analysis formulated abstract setting electrical-network models. Both, weak (segregated) strong (monolithic) approaches are studied, their stability limitations discussed. Being hybrid combination, quasi-simultaneous method, developed for partitioned aerodynamics, shown be robust flexible approach hemodynamic applications too. • Numerical strategies involving arteries have been studied. For arteries, method describing pressure difference can become unstable. design philosophy (aerodynamic) presented. A properly designed stable above application.
