I have modeled with Finite Element Analysis in the past. The version currently shipping is AutoSEA2. It was released in February of 1999. The excitation mechanisms may include complex acoustic fields, which is essential to treat problems such as propeller noise or aerodynamic noise.
New applications are under study in a number of companies.
The latter means that the results are usually in third-octave or octave bands, which makes comparison to test results easy. The former means that for a vibrating surface, the vibration level at a specific location is not predicted, but that instead an average value of the vibration level of all the points on the surface is given. This is usually a very meaningful quantity. In AutoSEA it is easy to study the effect of structural modifications on the noise and vibration environment of the product. For example we can modify the thickness or material of a panel, add ribs on it or replace it by a sandwich construction.
