MSC Integrates Actran, SC/Tetra for Aero-Acoustic Simulation

MSC_Logo_portoNEWPORT BEACH, CA, Apr 3, 2017 – MSC Software announced the coupling of its powerful acoustic simulation software Actran and SC/Tetra, MSC’s newest computational fluid dynamics (CFD) analysis system. This coupling of the two products provides users with highly accurate results of aero-acoustic simulations and better engineered designs for optimal fluid dynamics and acoustics performances.

Acoustic results computed by Actran software complement the aerodynamic analysis performed by SC/Tetra. The steady and unsteady results produced by an SC/Tetra aerodynamic analysis can now be exported in a CFD General Notation System (CGNS) format and subsequently used as the input to Actran to determine the aero-acoustic noise sources in given system. The acoustic propagation of these noise sources can then be calculated inside Actran to provide users with an accurate evaluation of the noise level and directivity of their designs.

Users can access this CFD/Acoustics coupling with MSC One, the token based licensing system that allows users to take advantage of MSC’s comprehensive solutions. Engineers now have access to a complete set of capabilities to study a large variety of applications such as noise from rotating fans, flow noise created by vehicle side mirrors, or air conditioning modules noise.

SC/Tetra and Actran are the perfect combination of software tools for engineers in the automotive industry, consumer electronics, electrical appliances, or industrial equipment fields.

“We are very enthusiastic about the new possibilities that our Actran users now have access to by our collaboration with MSC Software CFD Solutions. The remarkable synergy between SC/Tetra and Actran can benefit any engineer interested in designing products with superior fluid dynamic and acoustic performances,” says Benoit Van Den Nieuwenhof, CTO of Free Field Technologies.
