The integration of ANSYS and ANSYS CFX technologies using the ANSYS Workbench platform has taken a large step forward with release 11.0. Users are now able to set up, solve and post-process both one-way and two-way fluid structure interaction (FSI) simulations completely within the ANSYS Workbench platform. Significant attention and care has been given to ensure that the setup, solution and post-processing of an FSI calculation can be achieved with ease, while maintaining the necessary flexibility and practical functions required for the most demanding FSI cases. The latest release also provides a single post-processing tool whereby steady and transient FSI simulations can be viewed simultaneously within the ANSYS Workbench application, even supporting combined ANSYS CFX and FEA animation production. Core technology improvements have also been made, greatly extending the robustness and range of application for FSI. All of these changes make ANSYS Workbench 11.0 an extremely powerful platform for challenging FSI simulation needs.

Using the ANSYS fluid structure interaction capability, a thermal–stress simulation can be performed within ANSYS Workbench environment. For this gas engine exhaust header, thermal loads were passed from ANSYS CFX software to ANSYS Mechanical software to determine the heat transfer between the fluid and the solid body. From this information, the user determined stresses and ultimately performed a fatigue analysis. Pictures courtesy CADFEM. |
