| Research Abstract |
The achievements of this project are as follows.
(1) THINC scheme, which is an interface capturing method, has been improved. The accuracy of the free surface calculation is increased by the improved method for the case using moving variable meshes.
(2) A 6-DoF ship motion calculation method was developed by using quaternions. Numerical simulation of a ship in quartering waves has been successfully carried out by this method.
(3) Fluid structure interaction simulation based on Cartesian grid method was studied. A coupled approach with a finite difference method and a finite element method was developed for simulating the interaction between free surface flows and a thin elastic plate.
(4) A parallel version of the three-dimensional CIP based Cartesian grid code was developed. Very large-scale numerical simulations can be performed by the parallel code in PC cluster systems.
