Acoustics and noise simulation software

Actran is the premier acoustics software to solve acoustics, vibro-acoustics, and aero-acoustics problems. Used by automotive manufacturers and suppliers, aerospace, space and defense companies, and consumer product manufacturers. Actran helps engineers to better understand and improve the acoustics performance of their designs.

Actran provides a rich library of material models, a complete element library that includes infinite elements, high performance solvers to solve large size problems and a user-friendly GUI that is highly customizable to your needs. Actran, with its modular nature, can be deployed based on your applications and requirements.

Actran VI: Dedicated pre and post-processor for the Actran software family

Actran VI is the graphical user interface specifically designed for pre- and post-processing acoustics, vibro- and aero-acoustic analyses of all Actran modules. Including an Actran input file reader to check or modify input files generated by other tools, Actran VI supports several mesh formats (Nastran BDF, ANSYS RST and CDB, Actran DAT and NFF, I-DEAS UNV, Patran Neutral Format) as input for creating Actran input files.

Its various integrated pre-processing tools ease the creation and editing of Actran models. It is easy to visualize specific Actran model features (such as modal basis, sources or infinite elements coordinate system), to specify the projection parameters between incompatible meshes, to insert additional entities (e.g. control points) or to visualize the specified boundary conditions. Additionally, it is also possible to define analysis templates (with or without mesh) to ease the creation of recurrent analyses. The post-processing tool supports different results formats, such as OP2, UNV, NFF, RST, HDF and punch files. It contains different visualization modules, such as contour plots (maps), iso-surfaces, vectors or deformations, which can be freely combined and controlled using different filters. Synchronized viewports makes it easy to compare results at different frequencies, phases, times or related to different load case.
An animation module dedicated to complex harmonic results coupled with video export capabilities is
also included.
Actran VI includes the PLTViewer and WaterfallViewer modules for easily displaying and handling
frequency response functions, in single or multiple loadcases.

Sample applications:

  • Validation, visualization and modification of existing Actran analyses
  • Creation of new Actran analyses
  • Display reporting of all Actran results
