In article hemodynamic aspects of design of the artificial ventricles of heart (AVH) of systems of the auxiliary blood circulation (ABC) and the artificial heart (AH) on the basis of mechatronic modules are considered. Results of numerical modeling of hemodynamic processes of mechatronic modules of systems of ABC and AH proceeding in working hours which give an idea of behavior of blood in the AVH chamber are given. The AVH settlement model of pulsing type is developed in CAD-system Pro/ENGINEER WF5 taking into account influence of geometry of valves, entrance and output highways and membrane movement. For increase of accuracy of the decision splitting happened taking into account geometrical complexity of volume and nature of proceeding processes. It was expressed in a condensation of a grid of final elements in zones with high gradients of hydrodynamic parameters (speed, pressure, etc.) and the difficult geometry defining character of a current (braking, a recirculation of a stream, etc.). Possibility of use of systems of the final and element analysis for level definition hemolysis and forecasting of processes of a thrombosis is shown.
