Actran 17 Released

Free Field Technologies (FFT) has announced Actran 17. This release has new performance for acoustic, vibro-acoustic and aero-acoustic simulations.

New functionality in version 17 include transient aero-acoustic simulations, SNGR technology and mesh adaptivity updates.

Additionally, the company states vibro-acoustic analyses are now easier and faster than ever with new features and improvements such as:

• Mumps solver performance improvements allowing about 50% computational time speed-up;
• Support of Nastran OP2 files with multiple local coordinate systems
• Synthesis of TBL excitation through plane waves.

“Actran 17 delivers a valuable set of new features to the industry,” said Benoît Van den Nieuwenhof, CTO at FFT. “The enhancement of the time-domain solver with aero-acoustic capabilities opens the door to transient aero-acoustic analyses. In Actran, it is now possible to not only compute the noise generated by turbulent flows, but also from CFD simulations of transient phenomena. With this release, our team has also packaged helpful and easy-to-use tools for vibro-acoustic analyses such as the energetic post processing utility, a new wizard for space applications and new mesh adaptivity features.”
