On the Development of Human Body Simulator for the Next-Generation Supercomputer in Japan

The next generation supercomputer of 10 Peta flops speed is now under construction as a national project in Japan. Not only the hardware development but also the software development is highly expected and the software development for the human body simulator is assigned as a grand challenge program for the effective use of this supercomputer. In this program, the multiscale and multi-physics natures of the living matter are emphasized. Under this concept, we are developing the multiscale simulator for a living human body. Basic strategy of the simulator is to utilize the medical image data taken by MRI, CT, or ultrasound for the prediction of disease and planning of therapy. For this purpose, we have developed full Eulerian fluid-structure-interaction solver without mesh generation procedure, which enables us to conduct the simulations directly from medical images. The method is based on the finite difference scheme with fractional step algorithm for incompressible flows and materials. In the present talk, the current stage of the project is briefly introduced. Then, as one of the application software which utilizes the full Eulerian solver mentioned above, the multiscale thrombosis simulator is explained with the current stage of the development of the numerical methods. Future direction of our research and development is also discussed.
