| Abstract(in English) | Detailed simulation analysis of the cardiovascular system is important because the system is a biological phenomenon indispensable in maintaining life. Since the cardiovascular system is a result of the interaction of myocardial cell physiology, cardiac structural dynamics, and hemodynamics, it is necessary to use multi-physics simulation to couple equations of different scales. For a precise coupling simulation, it is desirable to use the strong coupling method which is computationally expensive. In this paper, a prediction method is proposed for a cardiovascular simulation system using strong coupling calculation. In the proposed method, the smoothing spline and extrapolators are used to predict an approximate solution to the convergence equation, using the predicted value as the initial value to decrease the number of iterations to convergence. Experiments are performed for different values of the smoothing parameter and first to fourth degree extrapolators. Decrease in iterations for the convergence calculation was observed when using the proposed method. |
