General Information

What is Coustyx?: Coustyx is a software program developed by Advanced Numerical Solutions (ANSOL), for computation of steady state sound fields. Coustyx integrates the Fast Multipole Method (FMM) with advanced Boundary Element (BEM) formulations to obtain rapid solutions to acoustic field problems. The small memory footprint of Coustyx, coupled with fast solvers allows simulation of very large problems (up to 1 Million DOF) in acoustics. For more details, Take a tour of Coustyx.; Back to Top
How to use Coustyx for trial runs?: First, download and install Coustyx on your local machine.

Where can I find Coustyx tutorials?: Step-by-step instructions on how to build Coustyx models and run acoustic analysis are available in Tutorials on Training Resources web page.; Back to Top
Why the surface element 154 is skipped while reading the ANSYS .rst file?: SURF154 is the ANSYS surface-effect element overlaid onto the area face of a 3-D element. These elements are used to apply surface loads or effects. In ANSYS workbench, SURF154 is automatically created to apply pressure or force loads. While importing structure geometry from ANSYS, Coustyx skips these elements to read only the 3D elements over which SURF154 elements are created.; Back to Top
Why do I get a bunch of warning messages about the data for a node not being found, while loading the frequency response data?: When there is a mismatch between the geometry and the frequency response data of a structure, you get the following message: "Data for node with ID:xxx was not found in the frequency response file." Make sure that the geometry and the frequency response data belong to the same mesh.; Back to Top

Other Information

Trouble-shooting windows uninstallation error: When Coustyx installation is not done correctly (or stopped prematurely), you can face the following error while uninstalling the software. "There is a problem with Windows Installer package. A program run as part of the setup did not finish as expected...". This prevents the user from uninstalling older version or reinstalling a newer version of Coustyx. You can resolve this problem by using "Windows Installer Cleanup Utility". For more information on how to download and use the "Windows Installer Cleanup Utility", visit http://support.microsoft.com/kb/290301. Read the instructions provided on their website carefully before using the software. Note that the "Windows Installer Cleanup Utility" only removes the Windows Installer Configuration information related to the program. It doesn't uninstall the program. But it, however, allows you to reinstall the program in the same folder. After cleaning up Coustyx using "Windows Installer Cleanup Utility", reinstall Coustyx in the same "Installation Folder". If the problem persists, contact support@ansol.com for assistance.; Back to Top
