SC/Tetra and Actran - Full Vehicle Wind Noise - Aero-acoustics

Demonstration case on the use of SC/Tetra and Actran for computing wind noise around a complete vehicle body up to 1500Hz.

- SC/Tetra computes the steady state flow around the vehicle.
- The SNGR method implemented in Actran is used to compute aero-acoustic sources due to flow turbulences.
- Actran DGM solver is used to propagate the aero-acoustic sources around the vehicle including complex reflections.

SC/Tetra and Actran are available with MSC Software licensing system MSC One.
