Numerical Simulation

‘Simulating reality, delivering certainty’ - Free Field Technology

With the advancements in computing power and software tools, numerical simulation plays an increasingly vital role in solving acoustics problems by providing insights into complex phenomena that are difficult to study through traditional experimental or theoretical methods.

ANV Consultants, as a Technology Partner for Hexagon Manufacturing Intelligence, provides numerical simulation for acoustics and CFD based on relevant Hexagon software suites

ACTRAN

ACTRAN (acronym of ACoustic TRANsmission, also known as the Acoustic NASTRAN) is the premier acoustic simulation software to solve acoustics, vibro-acoustics, and aero-acoustics problems. Actran is being developed by Free Field Technologies, a Belgian software company founded in 1998 by Jean-Pierre Coyette and Jean-Louis Migeot. Free Field Technologies is a wholly owned subsidiary of the MSC Software Corporation since 2011. Free Field Technologies and MSC Software are part of Hexagon AB since 2017.

ACTRAN includes the following simulation modules:

  • Actran Acoustics. Actran Acoustics is the foundation module of the Actran family. It is both a standalone tool and is a pre-requisite for advanced modules like Actran VibroAcoustics, Actran AeroAcoustics and Actran TM.
  • Actran VibroAcoustics. Actran VibroAcoustics is a robust, reliable and high-performing vibro-acoustic CAE module.
  • Actran AeroAcoustics. Actran AeroAcoustics predicts the noise generated by complex flows.
  • Actran SNGR. Actran SNGR predicts the noise generated by complex flows from steady CFD solutions.
  • Actran for Trimmed Body. Actran for Trimmed Body performs advanced vibro-acoustic analysis, combining Actran and MSC Nastran.
  • Actran SEA. Actran SEA is an efficient mid- and high- vibro-acoustic CAE module.
  • Actran TM. Actran TM is a CAE tool for turbomachinery noise prediction.
  • Actran DGM. Actran DGM predicts model noise propagation in complex flows.
  • Actran VI. Actran VI is a graphical user interface for pre- and post-processing vibro- and aero-acoustic analyses of all Actran modules.
