MSC.Actran--Powerful acoustic simulation tool

Belgian FFT (Free Field Technologies) was founded by Jean-Pierre and Jean-Louis in 1998. As early as a decade ago, Jean-Pierre and Jean-Louis realized that finite element technology and infinite element technology in the field of computational acoustics has broad prospects, so the beginning of the company focused on the FFT company based on finite element and infinite element of the calculation Acoustic software development, today when more computing acoustics software vendors are also aware of the finite element and infinite element technology in the acoustics of the leading position, the FFT company has been hard work in this field for ten years, all this makes the FFT Computing acoustics leader.

Actran is the flagship product of FFT. Actran was originally targeted at the spread of sound (hence the name Actran), which now covers all aspects of vibration acoustics and acoustics, with a wide range of features combined with today's most advanced technologies. Actran can deal with issues such as: acoustic radiation, scattering, closed and open sound field, pipeline propagation, convection effect, sound and vibration coupling, accurate simulation damping. Actran is easy to use, and CAE software integration is convenient; at the same time through engineering verification, with excellent robustness and efficiency. The company's professional support service is a powerful guarantee for your benefit.

Actran is the most complete acoustic simulation software on the market today. Based on the general technology of finite element and infinite element method, Actran provides a rich set of library, material library, boundary conditions, solution configuration and solver. Actran is used by the most discouraged engineers, researchers and teachers to solve challenging vibrational acoustics and acoustics problems.

As the technical leader in the field of computational acoustics, Actran's advanced nature is mainly reflected in the following four aspects:

Integrity

Actran contains a number of unique technical features in addition to all the features of other computing acoustics software, such as:

• Propagation of Acoustic Wave in Heterogeneous Moving Fluid

• The combination of physical coordinates and modal coordinate processing techniques increases the size of Actran's problem solving

• Contains simulations of echoed and unresponsive spaces

• Sound through the composite / sandwich structure of the transmission and absorption

• The engineering-oriented incentive and boundary conditions include: acoustic boundary conditions, diffusion field excitation, turbulent boundary layer excitation, rain-off excitation and stochastic kinematic excitation

Intrinsic consistency with other finite element software

Actran is based on a well-known, fully validated numerical technique - finite element method. Actran is therefore inherently consistent with other finite element programs and is easy to connect, combine, and compare with other major CAE tools.

Calculate performance

Actran contains a lot of characteristic solvers, such as Actran in the rapid calculation of frequency response function Krylov solver, not only a substantial increase in the efficiency of the solution, but also brings the following advantages:

• Calculate the frequency response function at least one order of magnitude faster than the traditional finite procedure.

• Close to the linear parallel acceleration ratio.

• Can be used for both damping systems and damping systems.

Integrated

• Actran has a seamless interface to NASTRAN, ABAQUS, ANSYS structural analysis programs.

• Actran has a direct interface to CFD programs such as Fluent, Star_CD, Star_CCM, Powerflow, Ensight, and a common HDF format interface for extracting sound sources and adding heterogeneous fluid effects.

• Direct integration with mainstream finite element front and rear processing tools, including I-DEAS Master Series, MSC.Patran and Hypermesh. Users can use the standard features of these tools as well as ACTRAN dialog boxes and icon menus with the same style.
