Outline of Final Research Achievements

We aimed to develop a high performance efficient computation system for fluid-structure interaction on a multi-core and/or parallel environment of the small laboratory. In three basic techniques of this system, a three-dimensional calculation was enabled about " Moving Embedded-grid method" and " Moving Computational Domain method". However, a two-dimensional calculation was only possible about "the sliding mesh method". Parallel calculations were performed by combining these methods. As a result, we obtained a calculation speed of 3.64 times at maximum in this system.
