| Outline of Final Research Achievements |
A simulation technology for respiratory lung motion is developed by using a particle method for solid mechanics. A motion model of the rib cage, a motion model of the diaphragm and a lung model are constructed and combined. The numerical results are validated by comparing with the medical images. Overall agreement is good. However a problem of sliding between the outer surface of the lungs and the inner surface of the rib cage is not solved. As the applications of the particle method to biomechanics, lymph flow in the semicircular canal, and swallowing and aspiration are analyzed. To improve the accuracy of the particle method, higher-order spatial discretization schemes, Arbitrary Lagrangian-Eulerian method employing the above schemes in the convection term, and wall boundary conditions using polygons.
