Recently, obtaining actual human heart shape as voxel data is easy via medical images. Our final goal is the realistic blood flow simulation of an actual heart using the voxel data to assist the diagnosis and treatment in daily medical scene. The heart shape is influenced by the cell behavior at each time, because blood flow is driven by heart contraction and the contraction occurred by cardiomyocyte cell behavior. Therefore considering the fluid-structure interaction driven the cardiomyocyte behavior that is cause of heart wall moving is necessary. Although structure analysis is usually performed based on the Lagrangian frame, we study the fluid-structure interaction simulation based on the Eulerian frame. In this simulation. both behavior flow and structure are analyzed by same way based on the same equation in the Eulerian grid. And the force computed by the cardiomyocyte model "Kyoto Model" drives the heart wall contraction. This interaction simulation system simulated a driving blood flow by cardiomyocyte contraction model.
