This paper deals with fast simulations of the hemodynamics in large arteries by considering a reduced model of the associated fluid-structure interaction problem. which in turn allows an additional reduction in terms of the numerical discretisation. The resulting method is both accurate and computationally cheap. This goal is achieved by means of two levels of reduction: first. https://www.jmannino.com/mega-save-Stephen-Chetham-Dogs-Bag-Isalbi-big-deal/
