Description
Summary:In this paper, development of a new Transmission Mesh method and its parallel implementation are presented. The Transmission Mesh method is a method where the body can move freely in the main mesh that covers the whole of the flow field. The method is developed for simulation of flows around multiple bodies that move and interact with each other in accordance with six degrees of freedom motion. An incompressible fluid/rigid sphere interaction is simulated. The parallel implementation based on the Domino method, which is a kind of block hyper-plane parallelism, is applied to the time-consuming Poisson solver. The parallel computation is performed using a multi-core processor with up to 24 cores, and its performance is tested.
