The paper presents the living heart finite element model, which can be used for heart beating simulation. The simulation of a human heartbeat is introduced in two settings – with artificial valves and tissue valves. The properties of tissue valves are similar to natural ones. The modelling was held using the FSI technology - fluid structure interaction – two-way coupling of the finite element model of the heart and the blood flow inside it. The finite element model of the heart was created as part of the Living Heart Project (the project of Simulia Dassault company).

The work deals with a hemodynamic library - an additional module for the FlowVision hydro-gasdynamic software package, which allows to set physical boundary conditions for projects related to modeling of the heart and blood vessels. The principle of the library is based on an electromechanical analogy.
