Prototype Implementation of a GPU-based Interactive Coupled Fluid-Structure Simulation

摘要

This paper reports a prototype implementation of 3D Fluid-Structure Simulation. In this implementation, heartbeat fluid flows inside a rectangular tube where the operator can interactively change the width of the tube. In order to achieve interactive simulation speed, some parts of the simulation is accelerated by GPU. For further improvement of the simulation speed, two techniques have been examined: the first one reduces the communication between CPU and GPU, and the second one offloads a whole fluid flow simulation onto GPU.
