MSC Software has partnered with Free Field Technologies of Belgium, to launch a vibro-acoustic software package called MSC.Actran.
The software uses finite element formulation for the acoustic elements. It can be used to model sound radiation, propogation (can handle non-uniform mean flow which makes it suitable for studying exhaust systems), enclosed sound fields, locally and non-locally reacting liners (suitable for modeling seats), sandwich panels (can handle constrained layer damping).
