Actran 16 Released

Acoustic propagations in huge domains and at high frequencies are now possible with Actran DGM code that supports GPU (graphics processing unit) acceleration.

For aeroacoustic capabilities, Actran 16 has the new SNGR module that synthesizes noise from inexpensive steady RANS solutions. Pellicular mode decomposition is also integrated for automotive side-window analysis and other acoustic contributions on non-rectangular and non-planar solutions.

The Actran time domain solver has been enhanced with solution capabilities and integration with MSC Software codes. Now, the software can read Dytran output files and has an updated interface with Adams.

Ease-of-use updates include several new tools for rapid creation and manipulation of vibro-acoustic meshes. Adaptive meshing technology has also been extended.

“Actran 16 delivers a valuable set of features to the industry,” said Benoît Van den Nieuwenhof, CTO at FFT. “The SNGR feature gives users access to new capabilities like full car exterior aero-acoustics where unsteady CFD computations are not affordable. For tackling higher frequencies and their associated model sizes, Actran features an original and automated mesh adaptivity. The Actran DGM solver leverages the latest HPC environments such as GP-GPUs which dramatically improves the computational efficiency of acoustic radiation analyses for automotive and aerospace industries”.
